4 month old sleep schedule
At 4 months, most babies take 3–4 naps with wake windows of 1 h 45 min to 2 h 15 min, and need 12–16 h of sleep in 24 hours.

- Naps a day
- 3–4
- Total sleep / 24 h
- 12–16 h
- Daytime sleep (sample)
- about 3 h 10 min
Around 4 months sleep architecture matures into adult-like cycles, which is why many babies start waking more (the "4-month sleep regression"). Most move from 4 naps towards 3.
Frequent waking at this age usually reflects development, not a schedule mistake. Consistent routines and putting baby down drowsy but awake can help.

Make it fit your baby
This schedule is built from the middle of the wake-window range for this age, with windows that lengthen through the day. If your baby fights naps, try stretching each window by 10–15 minutes; if they melt down before naps, shorten them. For a schedule from your baby's exact age, a sleep pressure clock and an AI helper for specific problems, use the baby sleep schedule calculator.
Feeding and sleep go together: see the 4-month-old feeding schedule for how much milk to expect at this age.
Safe sleep: the AAP recommends placing babies on their back on a firm, flat, empty surface, in the parents' room for at least the first 6 months.
Frequently asked questions
How long should a 4-month-old stay awake between naps?
A typical wake window at this age is 1 h 45 min to 2 h 15 min, with the shortest window in the morning and the longest before bed. Watch sleepy cues (staring, eye rubbing, yawning, fussing) rather than the clock alone.
How many naps does a 4-month-old take?
Usually 3–4 naps a day. Around 4 months sleep architecture matures into adult-like cycles, which is why many babies start waking more (the "4-month sleep regression"). Most move from 4 naps towards 3.
How much sleep does a 4-month-old need?
About 12–16 h in 24 hours, including naps. This is the range recommended by the American Academy of Sleep Medicine and endorsed by the AAP.
What time should a 4-month-old go to bed?
Counted from a 7:00 am wake-up, the sample schedule below lands bedtime at about 6:12 pm. Enter your baby's actual wake-up time to shift the whole day.
