2-3 Year Old Milestones: Your Toddler's Development from 24 to 36 Months

Yesterday they were saying "mama" as their first word; today they're insisting "mommy do it" for everything from buckling shoes to opening string cheese — and then, ten minutes later, "I do it MYSELF" for the exact same shoes.

Welcome to the year between two and three. This is the stretch where your toddler stops being a toddler-toddler and starts becoming a preschooler-in-training. Sentences appear. Pretend play explodes into storylines. They learn to jump, then pedal, then ask "why?" about everything from clouds to oatmeal. They also have epic meltdowns when the wrong cup comes out of the cabinet — because big skills and big feelings show up at the same time.

This guide walks you through what to expect across every area of development from 24 to 36 months: thinking, language, hands, social-emotional growth, senses, feeding, sleep, and play. We'll cover what's happening, which toys actually help, and when it makes sense to check in with your pediatrician.

One thing to keep in mind: every toddler has their own timeline. The ages here are ranges, not deadlines. The CDC notes that developmental milestones describe what most children (75% or more) can do by a certain age — so the "normal" range is wide.

🎭 Toddler Imagination & Pretend Play 2-3 Years: A Parent's Guide — the stages of pretend play, why open-ended toys win, what to look for if pretend play seems delayed, and how to scaffold without taking over.

(Fine motor and cognitive/spatial deep-dives are coming soon.)

Your Toddler at 24-27 Months: Two-Word Combos and Pretend Play Emerges

Key takeaway: Around 24-27 months, your toddler is putting two words together, running confidently, naming body parts, and starting to feed dolls and sort shapes — early signs of symbolic thinking.

This is the gateway. Your child is no longer the wobbly walker of a year ago, but they're not yet the chatty preschooler of next year. They're somewhere in between, and that in-between place is wonderful.

What's happening developmentally

Movement and language: According to the CDC Learn the Signs. Act Early milestones at 2 years, most toddlers are running, climbing on and off furniture, kicking a ball, and stringing two or more words together — "more milk," "doggie go," "mommy up." Many can point to at least two body parts when asked. The vocabulary explosion keeps rolling, and by 27 months a lot of toddlers have somewhere between 50 and 200 words, though the range is wide.

Thinking: This is where symbolic play clicks. Your toddler feeds a doll with a toy spoon, holds a phone (or a banana) to their ear, pushes a block across the floor with engine sounds. The AAP describes this pretend play as a major cognitive milestone — your child is showing they understand one thing can stand in for another. They're also beginning to sort by shape and color, find hidden objects, and complete simple shape sorters with help. A toddler nailing pretend play at 24 months and one just starting at 27 months are both normal.

Social-emotional: Independence is loud. "Me do it" is the song of the season. They watch other children with interest but mostly play alongside rather than with them — parallel play is still the norm.

What toys help at 24-27 months

The toys that work best now are simple, open-ended, and built to be handled. Wooden blocks, baby dolls with a few props (bottle, blanket, spoon), chunky puzzles with 4-6 pieces, ride-on toys, and a small basket of play food are all heavy hitters. Crayons (the thick kind that survive a fist grip) and board books with lift-the-flaps support both fine motor skills and language. Browse Toycycle's toddler collection for sturdy options that hold up to the throwing, chewing, and tower-toppling this age delivers.

Your Toddler at 27-30 Months: The Builder and the Pretender

Key takeaway: Between 27 and 30 months, three-word phrases appear, jumping with both feet shows up, vertical lines get copied, parallel play deepens, and pretend play gains props and storylines.

Your toddler is feeding the doll, then putting it in a stroller, then telling it "shhh, sleeping" — and somewhere in the last few months the doll-feeding stopped being a single act and turned into a sequence. That's the structural shift of this window. Pretend gains props, plans, and small storylines.

What's happening developmentally

Movement and hands: The CDC milestones note that by around 30 months, many toddlers are jumping with both feet, kicking a ball, and climbing on and off a couch unaided. Hands get more capable too: turning pages one at a time, building towers of about six blocks, and twisting doorknobs (a delightful new safety problem). They can copy a vertical line and may attempt circles. The WHO Multicentre Growth Reference Study, tracking gross motor milestones across six countries, found the typical range for independent jumping is broad — some children jump before 24 months, others not until close to 36. Both are normal.

Language: Three-word phrases show up — "I want juice," "daddy go bye," "more big truck." AAP HealthyChildren.org's Developmental Milestones for 2 Year Olds notes that toddlers this age follow two-step directions and start using pronouns, often imperfectly ("me do it," "him push me"). Some string four-word phrases; others are just getting comfortable with two. A child with 50 words at 28 months and one with 200 are both in normal range.

Thinking and play: Pretend gains props and sequences. Your toddler doesn't just hold the phone — they say "hi grandma," pause, then "bye." They line up cars, organize stuffed animals by some logic only they understand, and build taller, more deliberate towers. Parallel play deepens: they still play beside other children, but they're more aware of what those children are doing.

What toys help at 27-30 months

Pretend props go a long way: play kitchens, dolls with accessories, toy tools, animal figurines, vehicles. Add a set of blocks they can really build with (a generous quantity, not just six pieces), simple jigsaw puzzles in the 6-12 piece range, a low climber for indoor energy, and crayons or chubby washable markers. Variety matters here — having a few different pretend props on rotation lets the same afternoon turn into a vet clinic, a construction site, and a tea party. Toycycle's toddler collection is a good place to round out a pretend-prop bin without buying everything new.

Your Toddler at 30-36 Months: Grammar, Counting, and the "Why?" Phase

Key takeaway: From 30 to 36 months, sentences gain grammar, "I" and "me" come online, counting and color words appear, the "why?" loop kicks in, sharing is attempted (badly), and scissors enter the picture.

By the time your child is closing in on three, they sound and act like a small person rather than a toddler. The leap from 30 months to 36 months can be enormous.

What's happening developmentally

Language: According to the CDC Learn the Signs. Act Early milestones at 3 years, most children speak in three-or-more-word sentences, are understood by strangers most of the time, and ask "what" and "why" about everything. They use pronouns ("I," "me," "you," "we") with increasing accuracy. Vocabulary may climb past 500 words by the third birthday. They tell short stories ("we went park, saw doggie, doggie BIG"). A child speaking in clear three-word sentences at 32 months and one just getting there at 36 are both normal.

Thinking: Counting starts as a song, then as one-to-one correspondence. Many three-year-olds can count to three, then five, then ten — though "ten" may mean "a lot." They learn color words, name familiar shapes, and complete 3-4 piece puzzles. They begin to grasp "now" versus "later" and follow more complex directions. Pretend play becomes layered: a tea party has guests, courses, problems, and resolutions.

Social and fine motor: They attempt sharing — sometimes successfully. They take turns in simple games with help. According to AAP HealthyChildren.org, by 36 months many children hold safety scissors and make snips in paper, copy a circle, build a tower of 9-10 blocks, and string large beads. Toilet training readiness signs show up for many (more below). A 30-month-old with zero potty interest and a 36-month-old mostly trained are both normal.

What toys help at 30-36 months

This is where toy variety really matters. A core set: blocks (lots of them), a dollhouse or pretend kitchen, dress-up clothes, art supplies (crayons, washable markers, child-safe scissors, glue sticks), simple board games with turn-taking, beginner puzzles (12-24 pieces), threading and lacing toys, a tricycle or balance bike, and books — lots of books. This is also the age when art supplies get destroyed and puzzles lose pieces in the couch — both reasons buying secondhand makes sense. Toycycle's toddler collection is worth a look for the bigger items (dollhouses, kitchens, ride-ons) that get expensive new and rarely come home pristine anyway.

Fine Motor and Hands: From Stacking to Drawing to Snipping

Key takeaway: Between 24 and 36 months, hands go from stacking blocks and scribbling to drawing recognizable shapes, threading beads, and making the first cuts with safety scissors.

Watch a 24-month-old hold a crayon and a 36-month-old hold one and you're looking at two different relationships with the world. Between two and three, hands stop being grabbers and start being makers — moving from full-fist scribbles toward something that looks, briefly, like a drawn dog.

At 24 months, most kids have a refined pincer grasp and can stack 4-6 blocks, scribble with a fist grip, and feed themselves messily but effectively with a spoon. The AAP's HealthyChildren.org guidance notes that by 30 months tower-building reaches about six blocks, and your toddler can copy a vertical line and may attempt a horizontal one. The crayon grip shifts from full-fist toward a tripod grasp — though the mature grip is still years away.

Around 30-36 months, child-safe scissors enter the picture. The first attempts are wobbly snips at the edge of paper, not cutting along a line — that's exactly right. Snipping builds the hand strength and bilateral coordination needed for real cutting at 4 and writing at 5. Threading large beads, sticking and unsticking stickers, and pulling apart interlocking toys build the same small-muscle strength.

Drawing gets purposeful. By 36 months, most kids can copy a circle and may name what their scribbles "are," even loosely. ("It's a dog. And a tractor. And mommy.") Puzzles climb from 4-6 piece boards to 12-24 piece jigsaws for many three-year-olds.

A 30-month-old who avoids crayons and one who draws constantly are both within the normal range. What helps most isn't pushing outputs — it's low-stakes practice. Open the playdough. Set out the stickers. Let them try the scissors with supervision. The mess is the practice.

Thinking and Problem-Solving: Pretend Play, Categorization, Spatial Reasoning

Key takeaway: Pretend play is the cognitive main event of 2-3 — it builds language, executive function, and the symbolic thinking that underlies reading and math. Categorization and spatial reasoning take off in parallel.

If one developmental story defines the 2-3 year window, it's pretend play. Lillard et al.'s 2013 meta-analysis in Psychological Bulletin, "The impact of pretend play on children's development," found that pretend play is closely linked with growth in language, executive function, and social understanding. While pretend play may not single-handedly cause these gains, it's deeply intertwined with them and gives kids a context to practice them all at once.

In your living room: at 24 months, pretend is short and concrete — feeding the doll, talking on the phone. By 30 months, it gains props and sequence — putting the doll to bed, waking it up, making breakfast. By 36 months, pretend has plots, characters, and problems-with-resolutions. The dragon eats the cake; the firefighter saves the dragon; the firefighter needs a nap.

Two other cognitive threads run alongside. Categorization — sorting by shape, color, and function. They notice that ducks and cows are both animals, forks and spoons both for eating. Spatial reasoning — a block fits inside a cup, a tall tower needs a wide base, the puzzle piece has to rotate. Shape sorters, nesting toys, magnetic tiles, and chunky blocks are the workout equipment.

→ Full deep-dive on this stage of pretend play: Toddler Imagination & Pretend Play 2-3 Years.

What helps: give them open-ended materials and follow their lead. A wooden block can be food, a phone, a car, a baby, or a wall. A licensed toy that does one specific thing gets played with that one way, then forgotten. The toys that grow with your child are the ones that don't tell them what to do.

Language and Communication: Sentences, Stories, and the "Why?" Loop

Key takeaway: Two-word phrases at 24 months become three-word sentences by 30 months and short stories by 36 months. The "why?" phase, exhausting as it is, is a sign of real cognitive growth.

Language between two and three is one of the most visible leaps in childhood. According to the CDC Learn the Signs. Act Early milestones at 2 years, most toddlers use two-word phrases and follow two-step directions. By the 3-year mark, the CDC notes that most speak in three-or-more-word sentences, are understood by strangers most of the time, and ask a constant stream of questions.

Pronouns are messy at first and tidy up gradually. "Me want milk" at 27 months becomes "I want milk" by 33. The errors are useful — they show your child is learning grammar rules, not memorizing phrases. Plural and past-tense endings emerge with charming overgeneralizations ("I goed there," "two mouses").

The "why?" loop arrives around 30-33 months and can run for months. Why is the sky blue? Why? Some of it is genuine curiosity; some is a conversational tool — they've discovered "why?" keeps you talking. Both are worth honoring with a real answer.

Story-telling appears too. Your child narrates the past ("doggie barked, I cried, daddy came") and the future ("first park, then ice cream"). This is the start of narrative thinking, powerfully linked to later reading comprehension.

What helps is what helped at 12 and 18 months and will still help at 5: talk, read, and respond. Read books daily. Narrate your day. Ask open-ended questions ("what happens next?") instead of yes/no quizzes. Repeat what they said and add one new word — "you saw a big yellow dog!" A toddler with 100 words at 30 months and one with 400 are both in the normal range; steady growth matters more than count.

Social and Emotional Growth: Sharing, Self-Regulation, Big Feelings

Key takeaway: Tantrums are still developmentally normal — your child has growing feelings and growing skills, but the skills haven't caught up yet. Sharing is a slow build, and parallel play is still the dominant form of peer interaction.

If 12-24 months introduced tantrums, 24-36 months perfects them. According to AAP HealthyChildren.org's "Temper Tantrums" guidance, tantrums peak between 2 and 3 because toddlers have strong wants but limited ability to regulate disappointment, transitions, or being told no. This is normal — not a sign of bad behavior or bad parenting.

What helps: stay calm yourself. When you stay steady, you model regulation — a process called co-regulation. Your toddler learns to handle big feelings partly by watching you. Name the feeling out loud ("you're frustrated the block fell") without trying to fix it. Keep transitions predictable, sleep and food regular, and choices small ("red cup or blue cup?").

Sharing is the other big social story, and it's slow. At 24 months, sharing is aspirational — they may hand over a toy for two seconds and take it back. By 30 months, simple turn-taking with adult support emerges. By 36 months, sharing is real but inconsistent. It's a skill built over years, not months.

Parallel play (alongside, not with) dominates at 24 months and shifts toward cooperative play by 36. By 3, you'll see flashes of real collaboration — building a tower together, taking turns on the slide.

Empathy grows. Your toddler notices when others are upset, may try to comfort them, and shows pride in their own accomplishments. You'll also see the first flashes of self-consciousness — they may hide their face when they spill juice, or look away when a stranger says hi. That's social awareness coming online, not anything to worry about.

Sensory and Self-Regulation: Textures, Loud/Soft, and Sensory Seeking

Key takeaway: Sensory play is still a primary way your child learns. Loud, fast, climbing, splashing, and squishing kids are usually sensory-seeking — and that's developmentally normal. A choking-hazard sweep matters at every stage.

Toddlers from 24 to 36 months are still hands-on learners. Sand, water, playdough, finger paint, kinetic sand, rice bins, mud kitchens — the messier the better. Open-ended sensory play supports fine motor development, problem-solving, and emotional regulation. Pounding playdough is a coping skill.

Many toddlers show sensory preferences. Some seek loud, fast, big-movement input — climbing everything, crashing into pillows, sprinting. Others are more cautious. Both are typical. The question isn't "which kind of kid is mine" but "does this input regulate or dysregulate them?" Movement, jumping, water play, and outdoor time tend to help across the board.

Food textures often peak as a battleground here (more on picky eating below). Some kids love crunchy and refuse mushy; others want everything soft. This is normal sensory development.

A note on choking hazards: According to the AAP's "Choking Prevention" guidance on HealthyChildren.org, children under 4 are at high risk for choking on small toys and certain foods. Watch for small parts (anything that fits through a toilet paper tube), whole grapes, hot dog rounds, hard candies, popcorn, nuts, and chunks of raw carrot or apple. Cut food small, supervise meals, and check toys for loose parts. If older siblings have small-piece toys (LEGO, marbles, magnetic balls), keep those out of reach.

Feeding and Independence: Self-Feeding, Family Meals, Picky Eating

Key takeaway: Picky eating is normal at 2-3, not a problem to solve. Your job is to offer; their job is to decide. Toilet training readiness varies widely and rarely benefits from rushing.

If self-feeding was a project from 12-24 months, by 24-36 months it's a real skill. Your toddler uses a spoon and fork, drinks from an open cup, and can pour from a small pitcher (sometimes into the cup). By age 3, many can wash hands, dress with help, and put on shoes (often the wrong feet, which is part of the charm).

Picky eating. According to AAP HealthyChildren.org's "Picky Eaters" guidance, picky eating is the rule, not the exception, at this age. Your toddler's growth rate slows after infancy, and so does their appetite — they look pickier because they need less food. The AAP recommends the division of responsibility: parents decide what is offered and when; children decide whether and how much to eat. Don't pressure, bribe, or make separate meals. Keep offering rejected foods (it can take 10-15 exposures), eat together as a family, and trust your toddler's hunger cues. A child who eats three bites at dinner and two crackers at bedtime is usually getting what they need.

Toilet training readiness. According to AAP HealthyChildren.org's "Toilet Training" guidance, most children show readiness between 18 and 36 months — but the range is wide and rushing backfires. Readiness signs: staying dry for two-hour stretches, showing interest in the bathroom, telling you when they're wet or soiled, and pulling pants up and down. The AAP notes that boys often start a bit later than girls, and night training comes later than daytime training. A 2-year-old who's resisting and a 33-month-old who's enthusiastically using the potty are both within the normal range. Follow your child's lead.

Sleep and Routines: The Nap Transition (Again)

Key takeaway: At 2, your toddler still needs 11-14 hours of total sleep per day; by 3, the range shifts to 10-13 hours. Most kids drop their last nap somewhere between 2 and 4 years, with a wide range of normal.

According to Paruthi and colleagues' 2016 consensus statement in the Journal of Clinical Sleep Medicine — endorsed by the American Academy of Pediatrics — children aged 1-2 years need 11-14 hours of sleep per 24-hour period (including naps), and children aged 3-5 need 10-13 hours. The drop from one nap to no nap usually happens between 2 and 4 years.

Signs your child is ready to drop the nap: bedtime keeps shifting later, the nap itself is shrinking or being skipped, mornings are energetic, and afternoons aren't a meltdown zone. When the nap goes, an earlier bedtime usually saves you. A short "quiet time" with books in the old naptime spot can preserve some of the rest without requiring sleep.

Bedtime routines matter even more now, because your toddler is old enough to negotiate. A consistent order — bath, pajamas, teeth, two books, lights out — gives the bedtime brain something to count on. Night wakings are still common at 2 and drop off gradually through age 3. Bad dreams may show up around 3 as imagination develops; comfort, name the feeling, and stay close. A monster under the bed is the imagination working, not malfunctioning — the same brain that invents tea-party guests can also invent shadows.

A 27-month-old on a 45-minute nap and one still sleeping for two hours both fit within normal range. If nighttime sleep suffers, the nap stays; if nighttime is fine, the nap can shorten.

How You Play Matters More Than What You Buy

Key takeaway: Open-ended, simple toys outperform flashy electronic ones — and how you play (following their lead, narrating without quizzing, scaffolding pretend without taking over) matters more than the toys themselves.

The biggest research-backed conclusion about toys at this age: simpler is better. Sosa's 2016 study in JAMA Pediatrics, "Association of the Type of Toy Used During Play With the Quantity and Quality of Parent-Infant Communication," compared electronic toys, traditional toys (blocks, puzzles, shape sorters), and books during parent-toddler play. Electronic toys were associated with fewer adult words, fewer conversational turns, and fewer parent responses. The flashier toy did some of the talking, which left less for everyone else.

The AAP's clinical report by Yogman and colleagues, "The Power of Play" (Pediatrics, 2018), broadens the point: child-led, open-ended play with caregivers participating is so essential that pediatricians should treat it as part of well-child guidance. It builds language, executive function, problem-solving, and the parent-child relationship.

In practice:

• Follow their lead. If your toddler is hosting a tea party for stuffed dragons, you're a guest, not the director. "What kind of tea is this?" beats "Let's count the dragons."
• Narrate without quizzing. "You're stacking the red block on the blue one!" works better than "What color is this?" Quizzing shuts conversation down; narration opens it up.
• Scaffold without taking over. If they're stuck, offer one prompt — "the baby's hungry, what should we do?" — then go back to following.
• Choose open-ended over licensed. A generic doll can be anyone; a character doll is mostly that character.
• Resist the urge to fix. If the puzzle piece doesn't go in, wait. Their problem-solving is the point.

The best toys at this age are the ones still going strong in two years, when your toddler is a preschooler with bigger ideas about what a wooden block can become. Toycycle's toddler collection leans into exactly that — open-ended pieces that grow with your child rather than getting outgrown by the next birthday.

When to talk to your pediatrician

Every toddler develops on their own timeline, and the normal range is wide. Most kids who hit one of the items below later than expected turn out to be fine — but here's what's worth flagging at a well-child visit so your pediatrician can take a closer look. The AAP and CDC both recommend bringing specific things up at well-child checks. Worth mentioning:

• By 24 months: Doesn't use two-word phrases. Doesn't follow simple instructions. Doesn't copy actions and words. Doesn't notice when others are hurt or upset. Doesn't know what to do with common objects. Can't walk steadily.
• By 30 months: Doesn't use about 50 words. Doesn't engage in pretend play. Doesn't show interest in other children. Can't run. Has lost previously-gained skills.
• By 36 months: Doesn't speak in sentences. Doesn't make eye contact. Is hard to understand most of the time. Can't work simple toys. Doesn't play pretend. Drools constantly or has very unclear speech. Falls a lot or struggles with stairs. Can't draw a vertical line. Avoids or doesn't respond to other children or adults.
• At any age: Has lost skills. You have any nagging concerns at all.

These aren't reasons to panic — they're reasons to start a conversation. The AAP recommends formal developmental screening at the 30-month well-child visit (in addition to 9, 18, and 24). When parents have concerns, research shows they're often right. Early intervention services are available in every U.S. state for children under 3, and you don't need a doctor's referral.

Trust your gut and talk to your pediatrician.

Frequently Asked Questions

When do toddlers start pretend play?

The earliest signs of pretend play usually appear around 18 months — holding a phone up to the ear, feeding a doll. Between 24 and 36 months, pretend play becomes far more complex, with multi-step sequences, props, characters, and storylines. Research from Lillard et al.'s 2013 meta-analysis in Psychological Bulletin found pretend play is closely linked with growth in language, executive function, and social cognition. A 24-month-old who's just starting and a 30-month-old in full pretend mode are both within normal range.

Is it normal if my 2-year-old isn't talking in sentences?

At 24 months, most toddlers are using two-word combinations rather than full sentences — "more milk," "doggie go." The CDC milestones at 2 years list two-word phrases (not full sentences) as the typical marker. By 36 months, most children speak in three-or-more-word sentences and are understood by strangers most of the time. If your 2-year-old has fewer than about 50 words or isn't combining any words, mention it at the next well-child visit. Late talkers often do catch up on their own, but an early evaluation costs nothing and can shorten the wait if support helps.

When do toddlers start sharing?

Sharing develops slowly between 24 and 48 months. At 24 months, most toddlers don't share in any real sense — they may hand a toy over briefly and grab it back. By 30 months, simple turn-taking with adult support emerges. By 36 months, real sharing happens but is inconsistent. According to AAP guidance, sharing is a skill that's learned with help — not a default behavior — so adult-supported practice matters more than expecting it to "click" at any specific age.

How long should a 2-3 year old's attention span be?

Attention spans at this age are short and highly task-dependent. A loose rule of thumb is roughly 2-5 minutes of focused attention per year of age for a less-preferred activity, with much longer engagement possible for self-chosen pretend play. A 2-year-old might focus on a puzzle for 3 minutes but stay in a pretend kitchen scenario for 20. Variation is normal — what they're capable of shows up in the favored activity, not the boring one.

When should my toddler start preschool or structured learning?

The AAP supports child-led play as the primary "curriculum" for toddlers 2-3. Structured preschool isn't required at any specific age — many children don't start until 3 or 4, and that's perfectly fine. If your family wants the social experience, look for play-based programs that prioritize free play, peer interaction, and gentle routines over worksheets and academics. Children at this age learn best through play, not direct instruction.

Are tantrums at 2-3 still developmentally normal?

Yes, very much so. According to AAP HealthyChildren.org's "Temper Tantrums" guidance, tantrums peak between ages 2 and 3 because children have strong wants but limited regulation skills. Staying calm yourself, naming the feeling, and keeping transitions predictable all help. A small handful of patterns are worth a pediatrician conversation — tantrums that involve self-injury, last over 25 minutes regularly, or routinely include aggression toward others. But the everyday meltdowns at this age, hard as they are to live through, are normal.

What are red flags I shouldn't ignore at this age?

The CDC and AAP flag specific concerns: by 24 months, not using two-word phrases or not engaging in pretend play; by 30 months, fewer than 50 words or no interest in other children; by 36 months, not speaking in sentences, being hard to understand most of the time, not playing pretend, or losing previously-mastered skills. Any loss of skill, at any age, is worth a same-week call to your pediatrician. The AAP recommends formal developmental screening at the 30-month visit specifically because this is when subtle differences become clearer.

How much screen time is okay for a 2-3 year old?

According to the AAP Council on Communications and Media's 2016 policy "Media and Young Minds" (Pediatrics, 138(5):e20162591), children 2-5 should have no more than one hour a day of high-quality programming, with parents co-viewing. Background TV and solo screen time offer little benefit at this age. A thoughtful, co-viewed hour isn't a problem — but real play, conversation, and books still beat the best app.

What's next

Around your child's third birthday, the toddler era ends and the preschool era begins. Sentences get longer and more grammatical, pretend play becomes deeply collaborative with peers, friendships start to form, fine motor skills mature toward real drawing and pre-writing, and gross motor skills add hopping, galloping, and pedaling. Our 3-5 year development guide will cover everything to expect across that next stretch.
