Naps: How Many, How Long, and When to Drop Them

Nap schedules are one of the most common sources of confusion for parents of young children. How many naps does a baby need? How long should each one last? When is it time to drop a nap? The answers are more flexible than the rigid schedules in parenting books suggest.

The Rough Timeline

Newborns nap in short bursts throughout the day. By about four months, most babies settle into three to four naps a day. By six to eight months, most drop to two naps. The transition to one nap typically happens between 12 and 18 months, and most children drop the final nap between three and four years. These are averages, not deadlines. A child who still needs two naps at 14 months is not behind. A child who drops to one nap at 11 months is not ahead.³

Quality Over Quantity

Research has consistently shown that nap quality matters as much as nap quantity. A 2015 study in the Journal of Sleep Research found that naps that include a full sleep cycle, roughly 45 to 60 minutes for toddlers, are more restorative than shorter naps. A 20-minute catnap can take the edge off, but it does not provide the same cognitive benefits as a full cycle.

Signs It Is Time to Drop a Nap

The clearest sign that a child is ready to drop a nap is that they start resisting it. A child who takes 45 minutes to fall asleep at naptime, or who skips the nap entirely and is fine until bedtime, is signaling that they may be ready. The transition is usually gradual, with some days needing two naps and others needing one. Do not rush it. Dropping a nap too early often leads to an overtired child who sleeps worse, not better.

The Overtired Trap

One of the most counterintuitive findings in pediatric sleep research is that overtired children do not sleep better; they sleep worse. When a child is kept awake past their natural sleep window, their body produces cortisol and adrenaline, the stress hormones that keep them alert. These hormones make it harder to fall asleep, harder to stay asleep, and more likely that the child will wake early. The result is a cycle in which less sleep leads to more stress hormones, which leads to even less sleep.

This is why dropping a nap too early backfires. The parent sees the child resisting the second nap and assumes they no longer need it. But the resistance may be a sign of overtiredness, not readiness. A child who is truly ready to drop a nap will skip it and be fine. A child who is overtired will skip it and fall apart by late afternoon. The distinction matters, and it is worth observing for a week or two before making a change.

Nap Transitions: A Gradual Process

The transition from two naps to one is the most disruptive nap transition, and it typically takes several weeks to complete. During this period, some days will require two naps and others will require one. A useful strategy is the "bridge" approach: on days when the child skips the morning nap, move lunch earlier and offer an earlier afternoon nap to prevent overtiredness. On days when the child is clearly tired in the morning, offer the morning nap and a shorter afternoon nap. Over time, the single nap will stabilize, usually falling between 12 and 1 pm and lasting one to two hours.

The transition from one nap to no nap is similarly gradual. Most children between three and four years old will need a nap some days and not others. The "quiet hour," a period of rest without sleep, can bridge the gap. The child lies down with a book or a quiet toy, and if they fall asleep, they needed the nap. If they do not, the rest still provides a valuable break in the day.

The Bottom Line

Nap schedules are guidelines, not commandments. Every child is different, and the best schedule is the one that keeps your child rested and your family functioning. Watch your child, not the clock. Respond to signs of tiredness rather than fighting them. And remember that nap transitions are temporary storms, not permanent problems. The child who is fighting naps today will be ready for a new schedule tomorrow. The goal is not a perfect schedule. The goal is a rested child, and there are many paths to that goal.
