Milestones: 6–12 months
From sitting to first words, your baby's second half-year is full of big leaps — here's what to expect, and the wide range that's perfectly normal.
The 8–10 month sleep wobble
Around 8 to 10 months, big motor leaps and separation anxiety can shake up sleep that had settled — it's developmental, and it passes.
Progressing food textures
Moving your baby from smooth purees to lumps, finger foods and family meals helps them learn to chew, build skills and enjoy food with you.
Separation anxiety
That sudden clinginess and crying when you leave the room is a sign your baby loves and trusts you — it's a healthy stage you can gently support.

Common questions
How much should a 9 months old sleep?
Around 12–15 hours in total across a day and night is typical for a 9 months old, usually including 3 naps. Sleep needs vary widely between babies — use this as a guide, not a target.
How long should a 9 months old be awake?
Wake windows of about 2h 30m – 3h 30m between sleeps are typical at 9 months old. The first window of the day is usually the shortest. Watch your baby's tired cues rather than the clock.
How often does a 9 months old feed?
About 4–6 milk feeds a day, roughly every 3.5–6h, is common at 9 months old. Feed responsively to hunger cues.
Typical ranges for general information, not medical advice. Every baby is different; if your baby was born early, use their corrected age. For concerns, talk with your doctor or child-health nurse.
