Developmental Milestones in the First Year: What to Watch For

Why Milestones Matter

Developmental milestones are not a checklist to stress over — they are windows that help paediatricians and parents identify if a baby needs additional support early. Early intervention is significantly more effective than waiting.

Key Milestones by Age

2 Months

• Smiles socially in response to your face
• Follows moving objects with eyes
• Recognises parent's voice
• Holds head up briefly during tummy time

4 Months

• Laughs and squeals
• Reaches for objects
• Holds head steady without support
• Babbles and coos

6 Months

• Rolls from tummy to back and back to tummy
• Sits with support
• Transfers objects from one hand to the other
• Responds to own name

9 Months

• Sits independently
• Crawls or shows movement intention
• Pulls to stand with support
• Waves bye-bye, plays peek-a-boo
• Says "mama" or "dada" (may not be directed)

12 Months

• Stands independently for a few seconds
• Takes first steps (walking range is 9-15 months)
• Says 1-3 words with meaning
• Points at objects of interest
• Follows simple one-step instructions

Red Flags: Consult Your Paediatrician If...

• No social smile by 3 months
• Does not follow objects with eyes by 3 months
• No babbling by 6 months
• Does not respond to name by 9 months
• No gesturing (pointing, waving) by 12 months
• Loss of any previously acquired skill at any age

Dr. Sunita Rao's Note

Milestones have a range, not a single date. A baby who walks at 15 months is as normal as one who walks at 9 months. What matters is progression — continuous movement forward across all domains (motor, language, social, cognitive). If any domain appears stalled, that is worth discussing with your paediatrician.
