Newborn Wake Windows: A Simple Chart by Age
Wake windows are the stretches of awake time between sleeps that most babies handle well before they get overtired. Use this as a gentle guide, not a rule. Your baby is the expert.
| Age | Wake window | Total sleep per 24 hours |
|---|---|---|
Newborn (0 to 4 weeks) | 45 to 60 minutes | 14 to 17 hours |
1 to 2 months | 60 to 90 minutes | 14 to 16 hours |
3 months | 75 minutes to 2 hours | 14 to 15 hours |
4 to 5 months | 1.5 to 2.5 hours | 12 to 15 hours |
6 to 8 months | 2 to 3 hours | 12 to 15 hours |
9 to 12 months | 2.5 to 3.5 hours | 12 to 14 hours |
12 to 18 months | 3 to 4 hours | 11 to 14 hours |
18 months to 3 years | 4 to 6 hours | 11 to 14 hours |
Newborn (0 to 4 weeks)
Sleep comes in short bursts, day and night. Cue based feeding and sleep is normal.
1 to 2 months
Still mostly sleepy. Days and nights slowly start to sort themselves out.
3 months
Naps begin to lengthen a little. A longer stretch at night may appear.
4 to 5 months
Sleep gets more organized. Big developmental changes can shake things up.
6 to 8 months
Often three naps. Solids and separation awareness can affect sleep.
9 to 12 months
Usually two naps. Standing up in the crib is a common phase, not a regression.
12 to 18 months
Transitioning to one nap for many toddlers. Both one and two naps can be normal.
18 months to 3 years
One long midday nap. Big feelings and testing limits at bedtime are normal.
A gentle reminder
Wake windows shift day to day. Growth spurts, teeth, illness, and big developmental leaps all move the numbers. If a nap is short or a window is longer than the chart, your baby is still okay and so are you.
