Baby Sleep Schedule by Age: 0–18 Months Complete Guide

How much should your baby sleep, and when? A practical guide to wake windows, nap counts, and total sleep needs from newborn through 18 months — with sample schedules.

Why Sleep Schedules Matter

Babies don't come with built-in sleep schedules — they develop them. In the first weeks, sleep is entirely driven by hunger. By 3–4 months, circadian rhythms begin to mature and wake windows become predictable. By 6 months, most babies are ready for a more structured routine.

Getting the schedule right means fewer overtired meltdowns, easier bedtimes, and longer night sleep. Getting it wrong — napping too late, wake windows too long — leads to the kind of exhaustion that makes sleep worse.

This guide covers the key numbers for each age: how many naps, how long wake windows should be, and what total sleep to aim for.


Newborn (0–8 Weeks)

At this age, there is no schedule — and that's normal. Newborns sleep 14–17 hours per day in fragmented stretches of 2–4 hours, driven entirely by hunger and digestion.

What to focus on:

  • Feed on demand
  • Keep wake windows to 45–60 minutes — newborns tire very quickly
  • Dark, quiet environment for longer stretches
  • Don't expect night sleep consolidation before 8–12 weeks

2–3 Months

Sleep begins to consolidate slightly. You'll notice longer night stretches emerging (3–5 hours), and wake windows lengthen.

Target
Total sleep 14–16 hours
Night sleep 8–10 hours (with 2–3 feeds)
Naps 4–5 naps per day
Wake window 60–90 minutes

Sample schedule:

  • 7:00 Wake, feed
  • 8:15 Nap 1 (~45–60 min)
  • 9:30 Wake, feed
  • 11:00 Nap 2
  • 12:30 Wake, feed
  • 2:00 Nap 3
  • 3:30 Wake, feed
  • 5:00 Catnap
  • 6:30 Bedtime routine
  • 7:00 Bed

4–5 Months

The 4-month sleep regression typically hits here, changing sleep architecture permanently. Wake windows grow, naps begin to consolidate.

Target
Total sleep 14–15 hours
Night sleep 9–11 hours
Naps 3–4 naps
Wake window 1.5–2 hours

This is the age where tracking becomes most valuable. Watching actual data (not guessing) helps you catch the moment your baby transitions from 4 naps to 3.

6–8 Months

Most babies transition to 3 naps by 6 months and may move to 2 naps around 6–8 months. The third nap (late afternoon catnap) disappears first.

Target
Total sleep 13–15 hours
Night sleep 10–12 hours
Naps 2 naps
Wake window 2–3 hours
Bedtime 6:30–8:00 PM

Sample 2-nap schedule:

  • 7:00 Wake
  • 9:30 Nap 1 (~1–1.5 hours)
  • 11:00 Wake
  • 2:00 Nap 2 (~1–1.5 hours)
  • 3:30 Wake
  • 7:00 Bedtime

9–12 Months

Wake windows lengthen significantly. Most babies maintain 2 naps through 12 months, though some transition to 1 nap earlier. Watch for signs: nap refusal, hard time falling asleep at nap, taking much longer to fall asleep at bedtime.

Target
Total sleep 12–15 hours
Night sleep 10–12 hours
Naps 2 naps (watch for 1-nap transition)
Wake window 3–4 hours

12–18 Months

The 2-to-1 nap transition usually happens between 13–18 months. The transition itself takes 4–8 weeks and is one of the most challenging schedule shifts.

Signs your toddler is ready for 1 nap:

  • Consistently refusing one nap
  • Taking a very long time to fall asleep at nap
  • Napping late and then not sleeping at bedtime
Target
Total sleep 12–14 hours
Night sleep 11–12 hours
Naps 1 nap (1.5–2.5 hours)
Wake window 5–6 hours

Sample 1-nap schedule:

  • 7:00 Wake
  • 12:30 Nap (~1.5–2 hours)
  • 2:30 Wake
  • 7:30 Bedtime

How to Know If Your Schedule Is Working

A good sleep schedule looks like:

  • Baby falls asleep within 15–20 minutes of going down
  • Waking happy (not screaming) from naps
  • Handling wake windows without major meltdowns
  • Sleeping through the night (or waking only for feeds at younger ages)

If any of those are consistently off, the schedule is the first thing to examine. Track actual sleep times for 5–7 days before making adjustments — patterns you don't see when guessing become clear in data.

VINULU automatically shows you wake windows and highlights whether your baby is staying in range — and after a week of tracking, predicts when the next sleep window should be.
