What's developmentally happening at 15 months

Fifteen months is often when the move to one nap fully settles. Behaviorally, toddler independence grows — a 15-month-old may insist on walking instead of being carried, picking their own clothes, and rejecting help in general.

If still on two naps and nights are fine, there's no rush. If you've just transitioned, expect short naps and early wake-ups for a few weeks. Room darkening and a consistent wake time help.

Common sleep challenges at this age

  • Short single napNormal right after transition. Should extend within 3-4 weeks. Early bedtime bridges the gap.
  • Early morning wakesOften caused by bedtime being too early during transition. Nudge bedtime 15 min later every few days.
  • Toddler independence at bedtimeGive choices within the routine: 'PJs first or book first?'
