Sleep schedules by age

A schedule is a frame, not a rule

There are two ways to read a sleep schedule. The first is "she should be asleep at 1pm", and it almost always ends in frustration. The second is "a longer sleep is expected in the early afternoon", and it turns out to be useful. What drives infant sleep is not the time on the clock but how long your baby has been awake and how much sleep the day has held so far.

So read the examples below for their order and their intervals, not their hours.

0-3 months: rhythm instead of schedule

Newborns have not yet separated day from night; the body clock is still being built over the first weeks. Total sleep usually lands somewhere between 14 and 17 hours, but it arrives in chunks of two to four hours, tangled up with feeding.

A typical loop: wake, feed, 45 to 60 minutes awake, sleep again. That loop simply repeats. Fussing that builds through the evening is common at this age.

The only scheduling advice worth giving here is about the environment. Open the curtains at the first morning wake-up. Let daytime naps happen among ordinary household sounds. Keep night feeds dim and quiet. Babies learn the difference between day and night from their surroundings.

3-6 months: the day settles into three naps

Awake windows stretch to roughly 1.5 to 2.5 hours, and daytime sleep gathers into three main naps for most babies. Total sleep drops to around 12 to 16 hours, and the longest stretch of night sleep starts to lengthen.

A sample day: wake at 7am, first nap around 9am, a midday nap between noon and 1pm that is usually the longest, a short nap around 3:30pm, and the start of night sleep somewhere between 7pm and 8pm.

6-12 months: two naps and an early evening

Awake windows grow to between 2.5 and 4 hours, and daytime sleep drops to two naps: one mid-morning, one in the afternoon. Total sleep is around 12 to 15 hours. This is the first age at which a schedule really looks like a schedule.

A sample day: wake at 7am, first nap around 9:30am, a second and longer nap around 1pm, night sleep between 7pm and 8pm. If that second nap runs past 4pm, bedtime tends to slide later with it.

How to find your own schedule

Log wake-ups and sleeps for a few days in a row, then look at the order rather than the clock: how many naps there are, which one is longest, when the night begins. Agubu's rhythm chart stacks those days on top of each other, and the alignment usually shows up within a few days.

When the schedule falls apart

Illness, teething, travel, developmental leaps and a change of surroundings all scatter the day. A few disorderly days are ordinary, and the rhythm usually returns on its own. When a change lasts longer, rebuilding the whole day rarely works; fixing one point — most often the morning wake-up time — is easier and tends to pull the rest along.

When to see a doctor

• You notice pauses in breathing, snoring or effortful breathing during sleep
• Your baby is sleepy both day and night and is hard to rouse
• Weight gain has slowed, or feeding has clearly dropped off
• Sleep changed alongside fever, vomiting or unusual distress
• Night waking is getting steadily more frequent after six months and you cannot find a reason
• Your instinct tells you something is wrong

In an emergency, call your local emergency number.
