Baby Gross Motor Milestones 6-12 Months: Sitting, Crawling, and Standing
One day your baby is sitting with a pillow behind them "just in case." The next, they're army-crawling toward the dog bowl. Two weeks later, they've pulled themselves up on the bookshelf and are grinning down at you like they just climbed Everest.
Between 6 and 12 months, your baby's body catches up with their curiosity. They go from wobbly sitting to crawling (in one of many possible styles), then pulling up, cruising along furniture, and maybe — maybe — taking those first steps. It's one of the most dramatic physical transformations of the first year.
This guide covers the full gross motor arc from 6 to 12 months: sitting, crawling, standing, and cruising. We'll talk about what's actually normal (spoiler: it's a wider range than you'd think), what the WHO's global motor development study found, and what the AAP says about walkers, tummy time, and when to be concerned.
A quick note: every baby has their own timeline. The ages here are ranges, not deadlines. A baby who crawls at 7 months and one who doesn't crawl until 11 months — or skips crawling entirely — are all within the normal range.

What Gross Motor Skills Look Like at This Age
Key takeaway: Between 6 and 12 months, babies progress from sitting with support to potentially taking their first steps — but the order and timing vary more than most parents expect.
Gross motor skills are the big movements — sitting, rolling, crawling, standing, walking. They involve the large muscle groups in the trunk, legs, and arms. Everything your baby needs to eventually run, jump, and climb starts here.
The WHO Motor Development Study followed babies across five countries and found that about 90% achieved six key gross motor milestones in a common sequence. But the timing windows were wide. Sitting without support ranged from about 4 to 9 months. Walking alone ranged from about 8 to 18 months — a 10-month spread.
What this means for you: if your neighbor's baby walked at 9 months and yours is still happily crawling at 13 months, both are perfectly normal.
Sitting Up: From Wobbly to Steady
Key takeaway: Most babies sit independently between 6 and 9 months. The progression goes from tripod sitting (leaning on hands) to steady, hands-free sitting — and tummy time is what builds the strength to get there.
How sitting progresses
Sitting doesn't happen overnight. It's a gradual process:
- Tripod sitting (around 5-6 months): Your baby sits by leaning forward on their outstretched arms for balance. Take the arms away and they tip.
- Supported sitting (6-7 months): They can sit upright without leaning forward, but they're still a bit wobbly. A pillow behind them is smart insurance.
- Independent sitting (7-9 months): Steady enough to sit without support and lean sideways to reach for toys without toppling over.
- Getting into a sitting position (around 9 months): By 9 months, most babies can get themselves into a sitting position from lying down — a sign their core is genuinely strong.
The WHO study found the full range for sitting without support spans from about 4 months to 9 months across healthy babies worldwide. That's a wide window.
Why tummy time still matters at 6+ months
You might think tummy time is a newborn thing. It's not. By 6 months, babies should be spending even more time on their tummy — using it to play, pivot, roll, and reach. Tummy time builds the upper body and core strength that makes sitting, crawling, and every gross motor milestone after that possible.
If your baby resists tummy time, try getting down on the floor with them. Put a toy just out of reach. Use a rolled towel under their chest. Short, frequent sessions work better than long, frustrating ones.
Crawling: Not One-Size-Fits-All
Key takeaway: Babies typically start crawling between 7 and 10 months, but the style varies wildly — and about 4% of healthy babies skip crawling entirely.
When crawling usually starts
Most babies begin crawling between 7 and 10 months, though the WHO study found the full range stretches from about 5 to 14 months. Before forward crawling, many babies go through a predictable sequence: rocking on hands and knees, then scooting backward (because their arm muscles are stronger than their leg muscles), and finally figuring out how to go forward.
Six crawling styles (all normal)
Here's something that surprises a lot of parents: the AAP recognizes at least six different crawling styles, and they're all considered normal development.
- Classic crawl (cross crawl): One arm and the opposite knee move forward at the same time. This is the one most people picture.
- Belly crawl (commando crawl): Baby drags their torso along the floor, pulling with their arms. It looks like a tiny soldier in training.
- Bear crawl: Walking on hands and feet with straight arms and legs — like a little bear. It looks odd but it works.
- Bottom scoot: Sitting upright and scooting forward on their bottom, using their arms to propel themselves. Some babies do this exclusively.
- Crab crawl: Moving backward or sideways. This sometimes happens first because pushing is easier than pulling.
- Rolling crawl: Getting where they want to go by rolling from one place to another. Creative and effective.
What matters most isn't the style — it's that your baby is using both sides of their body in a coordinated way to move.
What about babies who skip crawling?
Some babies skip crawling entirely. They go from sitting to pulling up, cruising, and walking. This catches parents off guard, but the research is clear: it's not a problem.
The WHO Motor Development Study found that about 4.3% of healthy children across five countries never crawled on hands and knees. They hit all the other motor milestones just fine.
There's an old theory (the Doman-Delacato theory) that skipping crawling causes reading or learning problems later. The AAP has addressed this directly: there is no scientific evidence to support this claim, and it was disproven years ago through research studies. If your baby skips crawling but is otherwise meeting milestones — sitting, pulling up, showing interest in moving — there's no reason for concern.
The time to talk to your doctor isn't about crawling style. It's if your baby shows no interest in moving at all, seems very stiff or very floppy, or isn't reaching other milestones like sitting independently.
Standing and Cruising: The Upright World
Key takeaway: Babies start pulling to stand around 8-12 months, cruise along furniture soon after, and may walk independently anywhere from 8 to 18 months — the widest milestone window of all.
Pulling to stand
Once your baby figures out how to pull themselves up on furniture, they'll do it at every opportunity. The couch, the coffee table, your leg, the dog — anything that provides a handhold.
Most babies pull to stand somewhere around 8-12 months. The CDC lists pulling to stand and walking while holding furniture as 12-month milestones that most babies achieve.
Here's a common problem: your baby can get up but can't figure out how to get back down. They stand there, look panicked, and yell for help. This is normal. You can show them how to bend their knees and lower themselves — they'll get it with practice.
Cruising
Cruising — walking sideways while holding onto furniture — is the bridge between standing and independent walking. Your baby shuffles along the couch, moves to the coffee table, maybe makes the leap to a chair. They're figuring out weight shifting, balance, and how to move their feet while staying upright.
First steps
The WHO study found the window for walking alone ranges from about 8 to 18 months. That's a 10-month spread — the widest window of any gross motor milestone. Some babies walk at 9 months. Others don't walk independently until well past their first birthday. Both are normal.
Don't rush it. Walking will come when their muscles, balance, and confidence are ready.
Safety once they're upright
Once your baby is pulling up and cruising, the house looks different from their perspective — and everything they can reach is fair game.
- Stairs: Install sturdy safety gates at both the top and bottom. Babies are naturally drawn to stairs.
- Furniture: Anchor bookshelves, dressers, and TV stands to the wall. A baby pulling up on an unsecured piece of furniture can pull it over.
- Sharp edges: Corner guards on coffee tables and counters.
- Never leave them unsupervised in a room that hasn't been baby-proofed. They're faster than you expect.
Safety: Walkers, Jumpers, and What the Experts Say
Key takeaway: The AAP has called for a complete ban on baby walkers with wheels. They don't help babies walk sooner — and they cause thousands of injuries every year.
This is one of the clearest recommendations in pediatric safety: don't use baby walkers with wheels.
The AAP has called for a complete ban on their manufacture and sale. Canada has already banned them. Here's why:
- They're dangerous. A child in a walker can move more than 3 feet in 1 second — too fast for any adult to react. Most walker injuries happen while adults are watching. Injuries include falls down stairs (the most common, causing broken bones and head injuries), burns from reaching hot surfaces, drowning, and poisoning from reaching things that were previously out of reach.
- They don't help babies walk. Despite the name, walkers can actually delay when a child starts walking independently. They skip the muscle-building steps — the pulling up, the weight shifting, the balancing — that babies need to walk on their own.
What to use instead
- Stationary activity centers (no wheels, with rotating or bouncing seats) — these let babies stand and play without the mobility risks.
- Push toys where baby's feet are on the ground — like a toy shopping cart or push walker. These are different from sit-in walkers because the baby is supporting their own weight and practicing real walking mechanics. Weighted push toys are even better because they slow down and require more core muscle work.
- Activity tables the baby can stand at — especially good as they approach their first birthday.
- Floor time — honestly the best "equipment." It builds core, back, neck, and arm strength for every milestone.
One general principle: try not to keep babies in confining equipment (car seats, swings, bouncy seats, exersaucers) for extended periods during waking hours. Babies who spend too much waking time confined may experience delayed motor skills. Floor time is where the real development happens.
Toys That Support Gross Motor Development
Key takeaway: The best gross motor toys are the simplest — push toys, balls, and activity tables that give your baby a reason to move and something stable to hold onto.
You don't need a lot of gear. Here's what actually helps:
- Push toys and push carts — The kind where baby walks behind it holding the handle (NOT the sit-in kind). Weighted carts are best because they don't zip away when baby pushes. Look for a push toy where baby's feet are on the ground, supporting their own weight.
- Activity tables — Low, stable tables baby can stand at and play. Buttons, spinners, and sounds keep them engaged while they practice standing.
- Soft balls — Roll them, chase them, throw them. Balls motivate movement and introduce early social play (rolling back and forth).
- Tunnels — Crawling through a fabric tunnel is great motivation and builds confidence in movement.
- Empty boxes — Seriously. The CDC suggests letting babies push things around, like empty boxes, to practice walking. Free, effective, and babies love it.
- Floor space — The most underrated "toy." Clear a safe area and let your baby move freely. That's where skills develop.
In our experience, the toys that support open-ended movement outlast the ones that do just one thing. A push cart works for cruising at 10 months, walking practice at 14 months, and hauling stuffed animals around at 2 years.
When to Talk to Your Doctor
Key takeaway: You know your baby best. If something about their movement concerns you, speak up — there's no downside to asking.
Every baby has their own gross motor timeline. But here are specific things worth mentioning to your pediatrician:
- By 6 months: Doesn't push up on arms during tummy time. Seems very stiff or very floppy.
- By 9 months: Doesn't sit up without support. Doesn't bear weight on legs when held upright. Doesn't roll in either direction.
- By 12 months: Cannot stand when supported. Shows no interest in moving or exploring. Drags one side of body while crawling for more than a month.
- At any age: Has lost skills they previously had (regression). Muscles seem unusually stiff or floppy. Shows difficulty holding head and neck steady.
These aren't reasons to panic. They're reasons to have a conversation. The AAP recommends formal developmental screening at 9, 18, and 30 months — but screening can happen any time there's a concern.
Early intervention services for children under 3 can make a real difference. They can minimize and often prevent the long-term effects of developmental delays. And you don't need a diagnosis or doctor's referral to request an evaluation — you can contact your state's early intervention program directly.
The bottom line: you know your child best. If any of these concerns sound familiar, or if something just feels off about how your baby moves, speak up to your pediatrician. They'd always rather hear from you than not.

Frequently Asked Questions
When do babies start crawling?
Most babies begin crawling between 7 and 10 months, though the WHO found the full range stretches from about 5 to 14 months. Some babies skip crawling entirely and go straight to pulling up and walking. The crawling style varies too — classic hands-and-knees, belly crawl, bottom scoot, bear crawl, and more are all normal.
Is 5 months too early to crawl?
It's early but not impossible. The WHO study found some babies begin hands-and-knees crawling as early as 5.2 months. Most babies aren't crawling at 5 months — they're still working on sitting. But early crawlers do exist, and it's not a concern.
What if my baby skips crawling?
About 4.3% of healthy babies in the WHO study never crawled on hands and knees. The AAP has confirmed there's no evidence that skipping crawling causes learning or development problems. What matters is that your baby is moving, reaching milestones like sitting and pulling up, and showing interest in exploring.
When do babies pull themselves up to stand?
Most babies begin pulling to stand between 8 and 12 months. The CDC lists pulling to stand as a milestone most babies achieve by 12 months. Once they figure it out, they'll do it constantly — on furniture, your legs, the dog, anything stable enough to grab.
Do walkers help babies learn to walk?
No — the opposite. The AAP has found that walkers can actually delay independent walking because they skip the muscle-building steps babies need. The AAP has called for a complete ban on wheeled walkers due to injury risks. Use push toys (where baby's feet are on the ground) instead.
How can I help my baby learn to sit up?
Give them plenty of floor time and tummy time — these build the core strength sitting requires. You can sit behind them for support while they practice, gradually reducing how much you hold them. Place interesting toys just within reach to encourage leaning and reaching. Most babies sit independently between 6 and 9 months.
When do babies cruise along furniture?
Cruising typically starts shortly after pulling to stand, around 9-12 months. Your baby shuffles sideways while holding furniture, shifting weight from foot to foot. The CDC lists walking while holding furniture as a milestone most babies reach by 12 months.
What toys help gross motor development at 6-12 months?
Push toys (where baby walks behind them), activity tables, soft balls, tunnels, and simply having clear floor space. Weighted push carts are especially good because they're stable and don't slide away. Avoid sit-in walkers with wheels — the AAP recommends against them.
How much tummy time does a 9 month old need?
By 9 months, tummy time isn't a structured exercise anymore — it's a position your baby uses to play, pivot, roll, and reach. Aim for as much floor time as possible during waking hours, in a mix of positions including tummy, sitting, and moving. The more time on the floor (vs. in a bouncer, swing, or car seat), the better.
When should I worry about delayed gross motor skills?
Talk to your doctor if by 9 months your baby doesn't sit without support, doesn't bear weight on legs, or doesn't roll. By 12 months, concerns include not standing when supported, showing no interest in moving, or dragging one side of the body while crawling for more than a month. Loss of previously achieved skills at any age is always worth discussing.
