A sample day at 5 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

9:00am – 10:00am

Nap 1 — 2h awake, then about 1h asleep

12:00pm – 1:00pm

Nap 2 — 2h awake, then about 1h asleep

3:00pm – 4:00pm

Nap 3 — 2h awake, then about 1h asleep

6:00pm

Bedtime — 2h after the last nap ended

Each nap starts one wake window (2h) after the last sleep ended; bedtime is one more after the final nap. Nap length is assumed at about 1h.

What is typical at 5 months

Most babies settle into three naps around now, with the third a short one in the late afternoon.

Naps at this age: 3. Awake between sleeps: 1h 45m to 2h 15m. Longest night stretch: 6–9 hours at a time.

What most babies are doing by 6 months

The CDC does not publish a checkpoint at 5 months — its checkpoints are 2, 4, 6, 9, 12, 15 and 18 months. Your baby has passed the 4-month checkpoint and is working toward the 6-month one. These are the 6-month milestones, which is what most babies are growing into now.

Social and emotional

Knows familiar people
Likes to look at self in a mirror
Laughs

Language

Takes turns making sounds with you
Blows "raspberries"
Squeals

Learning and problem-solving

Puts things in their mouth to explore
Reaches to grab a toy
Closes lips to show they don't want more food

Movement

Rolls from tummy to back
Pushes up with straight arms during tummy time
Leans on hands to support self when sitting

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.
