Child Development Milestones: What Your Child Should Be Doing at Every Age

Child development follows a broadly predictable sequence — though with significant individual variation in timing. Understanding typical milestones helps parents identify when a child may need developmental support — and earlier identification means earlier intervention, when the brain is most responsive to therapy.

Milestones: Birth to 12 Months

2 months: Smiles in response to face; lifts head briefly when on tummy; makes cooing sounds; fixes and follows a face 180 degrees.

4 months: Laughs; holds head steady without support; reaches for objects; rolls from front to back.

6 months: Sits briefly with support; babbles (consonant-vowel sounds: ba, ma, da); passes objects hand to hand; looks for fallen objects.

9 months: Sits independently; pulls to stand; uses pincer grasp (thumb and finger); waves bye-bye; understands "no"; stranger anxiety appears.

12 months: Walks with support (cruising); 1–3 recognisable words with meaning (not just sounds); points to request; imitates simple actions; plays peek-a-boo purposefully.

12 to 24 Months

15 months: Walks independently; 5–10 words; points to body parts on request; scribbles with crayon; drinks from cup.

18 months: 10–20 words; follows two-step commands; identifies pictures in books; runs (though unsteadily); uses a spoon.

24 months: 50+ words; beginning to combine two words ("more milk", "daddy go"); runs well; kicks a ball; engages in parallel play.

2 to 5 Years

3 years: 3–4 word sentences; speech understandable to strangers (75%); pedals tricycle; dresses with help; plays with other children.

4 years: Fully intelligible speech; follows 3-step commands; draws a person with 4+ body parts; imaginative play; knows colours and counting.

5 years: Speaks in full sentences; counts to 10; knows letters; hops on one foot; independent toileting; school-ready.

Red Flags Requiring Immediate Evaluation at Any Age

• Any loss of previously acquired skills (language, motor, social) at any age — this is always a red flag
• No social smile by 3 months
• No babbling by 12 months
• No single words by 16 months
• No two-word phrases by 24 months
• Not walking by 18 months
• Not pointing to share interest by 14 months

"Boys talk later" and "she's just lazy" are dangerous dismissals that delay diagnosis and intervention. If you have a concern, seek evaluation — the cost of early evaluation is far lower than the cost of missed intervention.
