Motor milestones for your 9-to-12-month-old
By 9–12 months most babies sit steadily, crawl, pull to stand and may cruise along furniture, with a neat thumb-finger pinch emerging. These are guides, not deadlines — variation is normal, and a developmental screen helps if a skill is missing by 12 months.
In this answer 5 sections
Those first wobbly pulls to standing and the proud cruise along the sofa — between 9 and 12 months, your baby's body is rehearsing for a lifetime of moving.
In short
Between 9 and 12 months, most babies sit steadily without support, crawl or shuffle, pull up to stand, and may begin cruising along furniture. Hands grow precise too — a neat thumb-and-finger pinch appears. These are guides, not deadlines: babies arrive at each skill on their own timeline, and a little variation is completely normal.
What you may see (9–12 months)
Big movements (gross motor)
- Sits steadily and turns to reach a toy without toppling
- Crawls, bottom-shuffles or commando-crawls to get around
- Pulls up to stand holding furniture
- Cruises sideways along the sofa; some take first steps near 12 months
Hand skills (fine motor)
- Picks up tiny things with a neat thumb-and-finger pinch
- Bangs two objects together, lets go of toys on purpose
- Pokes with one finger; begins finger-feeding
The science
The WHO ICF groups these under neuromusculoskeletal and movement functions (b7). Motor growth flows head-to-toe and centre-outward — trunk control first, then standing and walking, while grasp refines from raking to a precise pinch. Floor time and reaching practice are how the brain wires this.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional. If you'd like a closer look, explore our motor milestones guide, occupational therapy for hand and movement skills, and learn what the AbilityScore® is and how it's used.
Trusted sources
Guided by the WHO ICF framework for movement functions (b7) and consistent with CDC and AAP developmental milestone guidance for the first year.
Next step — if your baby isn't bearing weight on legs, sitting steadily, or using both hands equally by 12 months, book a gentle developmental screen with our team.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Speak to a clinician if by 12 months your baby is not bearing weight on legs when held standing, not sitting without support, not crawling or moving across the floor, or consistently favours one hand over the other.
In everyday life
Give plenty of supervised floor time on a firm surface and place favourite toys just out of reach — reaching, pivoting and pulling up are how those muscles and the brain rehearse standing and walking.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
My 11-month-old isn't crawling yet — should I worry?
Not necessarily. Some babies skip crawling and go straight to cruising or bottom-shuffling. What matters more is steady progress overall — sitting well, bearing weight on legs, and using both hands. If your baby isn't moving across the floor at all by 12 months, a developmental screen offers reassurance and guidance.
When should a baby start walking?
Walking has a wide normal range — some take first steps around 12 months, many not until 15–18 months. By 9–12 months, pulling to stand and cruising along furniture are the milestones to look for. Independent walking comes after.
What is a pincer grasp?
It's the neat pinch using the tip of the thumb and index finger to pick up tiny objects, like a crumb or pea. It usually appears between 9 and 12 months and is an important fine-motor milestone for self-feeding and later skills.
