How to Help Your Baby Sleep Better

Sleep windows, tired cues, and the routine that works.

There's no such thing as a "baby who sleeps through the night" in the first months — that's biology, not bad habits. But there are strategies that make a real difference. The key: respect your baby's sleep windows.

Sleep windows by age

0-2 months

45-60 minutes awake between naps. Gets tired very fast.

3-4 months

60-90 minutes awake. This is when sleep regression hits.

5-6 months

2-2.5 hours awake. Starts consolidating naps (3 naps/day).

7-9 months

2.5-3 hours awake. Transitioning from 3 to 2 naps.

10-12 months

3-4 hours awake. 2 stable naps, bedtime ~7:30pm.

Tired cues (act before crying)

  • Rubbing eyes or ears

  • Yawning (note: if yawning a lot, may already be overtired)

  • Glazed look, less eye contact

  • Less interest in playing or surroundings

  • Sudden irritability without apparent cause

Bedtime routine (20-30 min)

  • Same time, same order, every night — the brain learns the pattern

  • Bath → massage → pajamas → calm feeding → song → crib

  • Dark and cool room (18-20°C / 64-68°F is ideal for sleep)

  • Constant white noise — helps ignore household noises

💡

Always on their back to sleep, on a firm flat surface, without pillows or loose blankets. No bed-sharing. (AAP Safe Sleep 2022)

The sleep window: put your baby down BEFORE they're overtired. If they're already crying, you've missed the ideal moment.
