## TLDR

- Rolling around 4-6 months, sitting alone 6-9 months, then crawling and walking, with wide normal ranges.
- Daily floor time and fewer containers help. Skip baby walkers: they cause injuries and don't speed walking.
- Check in about no rolling by 6 months or no sitting by 9. Losing a skill always needs a prompt check; Early Intervention evaluations are free.

## Typical ranges

Motor skills come in a rough order, but timing varies widely. If your baby was born early, use
the age from their due date until about age 2.
- **Rolling:** usually tummy to back first, around 4 to 6 months, then back to tummy.
- **Sitting:** propped on their hands around 5 to 6 months; sitting steadily without support
  around 6 to 9 months.
- **Crawling:** often 7 to 10 months, but styles vary: belly commando crawls, scooting on the
  bottom, rolling across the room. Some babies skip crawling altogether and go straight to
  pulling up and walking. That alone isn't a concern if they're moving and using both sides.
- **Pulling to stand:** around 9 months, often on furniture or your legs. At first they can't
  get down; help them practice bending their knees.
- **Cruising:** walking sideways while holding furniture, around 9 to 12 months.
- **Walking:** first independent steps anywhere from about 9 to 18 months. Many walk around 12
  months; a later walker within that range is usually just a later walker.

## What helps

- **Floor time, every day.** A safe, open floor and supervised tummy time from the first weeks
  build the strength for every later skill. See the tummy time guide.
- **Less time in containers.** Car seats (outside the car), bouncers, swings and seated activity
  centers keep babies still. Short stretches are fine; long ones take away practice.
- **Put toys just out of reach,** and give them sturdy furniture to pull up on. Push toys that
  are stable and that they walk behind can help once they're standing.
- **Let them fall a little.** Small tumbles on a soft surface are how balance is learned.
  Babyproof first; see the babyproofing guide for crawlers and climbers.

## No baby walkers

- The AAP advises against mobile baby walkers and has called for a ban on their sale. Walkers let
  babies roll fast toward stairs, hot surfaces, pools and things to pull down, and cause thousands
  of injuries a year, including skull fractures.
- They don't help babies walk sooner and may delay it. A stationary activity center is the safer
  choice, for short periods.

## Bare feet and first shoes

- Barefoot is best indoors. Feet grip and balance better, and muscles and arches develop
  naturally.
- Once walking outside, choose shoes for protection: light, flexible soles, a roomy toe box, and a
  snug heel. Avoid stiff or high-top "support" shoes; healthy feet don't need them.
- Flat feet, in-toeing, bowed legs and walking on tiptoes now and then are all common in new
  walkers and usually straighten out.

## Bring it up at the checkup if

- By 4 months, your baby can't hold their head steady, or doesn't bring hands to mouth.
- By 6 months, they don't roll at all, or don't reach for toys.
- By 9 months, they can't sit without support.
- By 12 months, they don't pull to stand or bear weight on their legs.
- By 18 months, they aren't walking on their own.
- They use one side of the body much more than the other, seem very stiff or very floppy, or
  walk only on their toes all the time.
- You're worried, even if they're within the ranges.

## Talk to the doctor soon if

- Your baby loses a motor skill they had, at any age. That always needs a prompt check.

## Free help

- In the US, children under 3 can get a free developmental evaluation through the state's Early
  Intervention program. You can call yourself; no referral is needed. Physical therapy, if
  needed, can start early and works best early.
