A sample day at 10 months

Built from a 7:00am wake-up. Change the wake time in the tool to shift the whole day.

7:00am

Wake for the day — your input

10:23am – 11:38am

Nap 1 — 3h 23m awake, then about 1h 15m asleep

3:01pm – 4:16pm

Nap 2 — 3h 23m awake, then about 1h 15m asleep

7:39pm

Bedtime — 3h 23m after the last nap ended

Each nap starts one wake window (3h 23m) after the last sleep ended; bedtime is one more after the final nap. Nap length is assumed at about 1h 15m.

What is typical at 10 months

Some babies start refusing the second nap around now. Refusing it for a few days is not the same as being ready to drop it — the transition to one nap is usually later.

Naps at this age: 2. Awake between sleeps: 3h to 3h 45m. Longest night stretch: 10–12 hours at a time.

What most babies are doing by 12 months

The CDC does not publish a checkpoint at 10 months — its checkpoints are 2, 4, 6, 9, 12, 15 and 18 months. Your baby has passed the 9-month checkpoint and is working toward the 12-month one. These are the 12-month milestones, which is what most babies are growing into now.

Social and emotional

Plays games with you, like pat-a-cake

Language

Waves "bye-bye"
Calls a parent "mama"/"dada" or a special name
Understands "no" (pauses or stops)

Learning and problem-solving

Puts something in a container
Looks for things they see you hide

Movement

Pulls up to stand
Walks holding on to furniture ("cruising")
Drinks from a cup without a lid, with help
Picks up small things with thumb and finger

The CDC does not link these milestones to sleep, and neither do we. They are here because much of what changes about sleep at a given age is really what is changing about the baby. Source: CDC, Learn the Signs. Act Early.

Safe sleep, source conflicts and what this is not — the AAP safe-sleep rules, where the AASM and the National Sleep Foundation disagree, and why this is not a sleep-training method: read the full guidance notes. General guidance, not medical advice.
