What most children are doing around 9 months
These are milestones most children — 75 percent or more — can do by this age, from the CDC’s 2022 “Learn the Signs. Act Early.” checklists, with Canadian guidance from the Canadian Paediatric Society. Think of it as a picture of typical, not a finish line. Last reviewed 2026-07-03.
This isn’t a quiz, and there’s nothing to score. You can’t fail it and neither can your child. It’s a way to enjoy noticing what’s emerging — and to know what tends to come next.
Social and emotional
- is shy, clingy, or fearful around strangers
- shows several facial expressions, like happy, sad, angry, and surprised
- looks when you call their name
- reacts when you leave, by looking, reaching for you, or crying
- smiles or laughs when you play peek-a-boo
Language and communication
- makes a lot of different sounds, like "mamamama" and "bababababa"
- lifts their arms up to be picked up
Cognitive — learning and problem-solving
- looks for objects when dropped out of sight, like a spoon or toy
- bangs two things together
Movement and physical
- gets to a sitting position by themselves
- moves things from one hand to their other hand
- uses their fingers to "rake" food towards themselves
- sits without support
Every child is different
All children develop skills at different times — the Canadian Paediatric Society notes it’s normal for a child to be ahead in some areas and still emerging in others at the same time. A child who took their first steps “late” and one who took them “early” usually both end up running around the playground. If your child was born early, look at their corrected age: their actual age minus the weeks they arrived early.
Canadian Paediatric Society — child developmentWhen it’s worth a chat with your provider
You know your child best — that’s the CDC’s own starting point. It’s worth mentioning to your child’s doctor or nurse practitioner if: your child isn’t meeting one or more of the milestones on their age’s list; your child has lost skills they once had (this one matters at any age); or something just feels off to you — a parent’s concern is reason enough.
None of these mean something is wrong. They mean a conversation is useful, because if support is ever needed, earlier is easier. What to ask for: a developmental screening (routinely recommended around 9, 18, and 30 months, with autism screening at 18 and 24 months); if concerns remain, a referral to a specialist; and in Canada, your provincial or territorial early-intervention or child-development program — you don’t need to wait for a diagnosis to ask.
