Audience
Parents of children aged 6 months to 5 years dealing with nap transitions or early morning waking

TL;DR

  • ·Nap cessation follows a wide developmental range — in a Swiss cohort, about 50% of 3-year-olds still napped, about 35% at four, and fewer than one in five at five — and the turbulence of each transition (earlier bedtimes, more night waking) is normal physiology, not a parenting failure
  • ·Seven consecutive days of logged bedtime and wake time reveals whether early morning waking reflects adjustable sleep pressure or an innate early chronotype that bedtime shifts alone cannot fix
  • ·During the two-to-one nap transition, moving bedtime 30–45 minutes earlier for one to two weeks compensates for the lost daytime sleep and reduces late-afternoon fussiness

"At eight months, the morning nap just stopped." "Dropping from two naps to one sent the late afternoon into chaos." "At daycare they still nap; at home they won't." "Every morning: 5 a.m."

Nap transitions are among the most opaque sleep changes in early childhood. The timing varies widely between children, and nothing you did caused the transition to happen — or to stall. This article maps the nap transition timeline and the structure behind early morning waking.

The memori app is built so you can check these patterns against your records instead of your memory.

  • Bedtime sessions: time-to-sleep accumulates separately for each method you try — rocking, lying down beside them, white noise.
  • A per-night tally of how many feeds and wakings there were.
  • White noise and ambient sound, with a caution when the volume climbs too high.
