Every baby develops at their own pace; milestones are guiding ranges, not hard limits. Still, a marked delay in certain signs can be a signal for early support. Noticing early means helping early.
This content is educational. If you're worried, don't wait — talk to your pediatrician. For preterm babies, milestones are assessed by corrected age.
Approximate milestones
2 months: Reacts to sound, smiles, follows a face, briefly lifts head during tummy time.
6 months: Nearing sitting without support, reaches for objects, babbles, responds to familiar faces.
9 months: Sits with/without support, transfers objects hand to hand, looks when called, shows stranger anxiety.
12 months: Pulls to stand, a few words like "mama/dada", simple gestures (waving), pointing.
18 months: Walks, a small vocabulary, understands simple instructions, pretend play begins.
24 months: Runs, starts two-word phrases, simple play, attempts to eat with a spoon.
'Act early' red flags
These don't make a diagnosis on their own, but they warrant evaluation:
- No eye contact, no social/responsive smile.
- No babbling or turning to sounds by 6 months.
- No gestures like pointing or waving by 12 months.
- No words by 18 months.
- Loss of a previously gained skill (regression) — always important.
- Marked floppiness or stiffness, or one-sided use.
How to support development
It's interaction, not expensive toys, that builds development: talking, naming, looking at books together, imitation games, a safe space to explore, and enough room and time. At this age, screens shouldn't replace interaction.
Tracking and measurement
Follow development through regular health checks. When growth percentiles (height, weight, head circumference) and developmental milestones are read together, you get a clearer picture of the child's overall status.
