How much daytime sleep does a baby need? A nap chart by age

How many hours of daytime sleep and how many naps a baby needs, by age — with a simple nap chart and the signs your baby is running short.

If you have ever stared at the clock wondering “is my baby getting enough daytime sleep?” — you are asking exactly the right question. Naps aren’t optional extras. They are where a big chunk of a baby’s total sleep happens, and getting the daytime total roughly right is what protects the night.

The tricky part is that “enough” keeps changing. A newborn sleeps in scattered bursts around the clock; a toddler consolidates down to a single afternoon nap. The chart below is the map most pediatricians use as a starting point.

Daytime sleep and naps by age

These are typical ranges. Every baby is different — treat them as a starting point, then adjust to yours.

AgeDaytime sleepNaps / day
Newborn (0–3 months)5–8 hrs4–6 (irregular)
2–3 months4–6 hrs3–5
4–5 months3–4 hrs3–4
6–8 months2.5–3.5 hrs2–3
9–12 months2–3 hrs2
12–18 months2–2.5 hrs1–2
18 months–2 yrs1.5–2.5 hrs1

Notice the total daytime hours shrink as your baby grows, and the number of naps drops too. Transitions between these stages are usually where naps get bumpy for a couple of weeks — that’s normal, not a sign anything is broken.

Signs your baby is running short on naps

The clock is a guide; your baby’s behavior is the real signal. A nap deficit tends to show up like this:

  • Waking up cranky. If your baby wakes crying, rubbing their face and refusing to play for the first 15–20 minutes, they probably didn’t finish a sleep cycle. A rested baby opens their eyes calmly and gets going quickly.
  • Micro-naps in arms or the high chair. Nodding off in the car at 6 p.m., dozing during dinner, or drooping on the changing table usually means the day’s naps didn’t add up. The body grabs sleep wherever it can.
  • More night wakings, not fewer. It’s counterintuitive, but a baby who under-naps often sleeps worse at night. By bedtime they’re so overloaded that night sleep turns fragile. More daytime sleep, fewer wakings.

Length matters as much as count

A string of 30-minute cat naps rarely feels as restorative as one or two solid stretches. If your baby wakes exactly at the 30- or 45-minute mark and seems tired, they may be surfacing between cycles rather than linking them. Nap length and nap timing work together — and timing comes straight from getting the awake stretches right, which is where wake windows by age come in.

The easy way to see the pattern

Judging the real length of each nap in the day-to-day fog is genuinely hard, and the totals shift week by week. This is where Nana helps — you log naps with a tap, and over a week or two it surfaces your baby’s actual pattern, so you can see at a glance whether the daytime total is landing where it should for their age.

Every baby is different, and none of this replaces your pediatrician. These ranges reflect widely used infant-sleep guidance; if your baby is consistently far outside them, or something feels off, ask your doctor.

Quick answers

How much daytime sleep does my baby need?

It depends on age. A newborn may sleep 5–8 hours across many short naps, while a one-year-old often needs about 2–3 hours in one or two naps. These are ranges — the right amount is the one that leaves your baby settling well and waking rested.

How do I know if my baby isn't napping enough?

Common signs of a nap deficit are waking up crying and irritable, drifting off in the car or high chair late in the day, and — counterintuitively — more night wakings. A rested baby usually wakes calmly and gets going quickly.

Do the hours in the chart have to be exact?

No. They are typical ranges, not targets to hit. Some babies nap more, some less, and days vary. Watch your baby and use the chart as a guide rather than a rule.
