When Do Babies Drop to One Nap? Signs and Transition Tips

As a certified child sleep consultant, I know the transition from two naps to one can be a doozy. Your little one may start skipping a nap or taking shorter naps, leaving you wondering whether to change the schedule or give it more time. I’m sharing the signs to watch for and ways to help with the adjustment.

The tips below are written with children who can fall asleep independently in mind. If your little one still needs help settling, you may need to adapt the approach to the support they usually need.

Many children transition from two naps to one between 12 and 18 months, although the timing varies.³ By around 18 months, most toddlers are taking one afternoon nap.¹ Watch your child’s sleep pattern as well as their age when deciding whether to make the change.

Signs Your Child Is Ready to Drop to One Nap

Look for a pattern over several days, rather than making the change after one skipped nap. These signs can suggest it is time to review the schedule, but none proves on its own that your child needs only one nap.

1. Boycotting One or Both Naps

The most common sign your little one is ready to transition to one nap is simply not taking them. Many babies will play in their crib during the morning nap rather than sleep. Or your baby might take a beautiful morning nap and then not sleep during their afternoon nap. If this continues for about two weeks, it may be time to try one nap, especially if your child is otherwise managing well with longer periods awake.

2. Naps Are Much Shorter Than Usual

Another sign is when your little one starts taking two SUPER short naps. I’m talking 30–45-minute naps when previously the naps were 1–1.5 hours each! One afternoon nap often lasts about 1.5–3 hours, but length varies, and it may not become longer immediately after the transition.¹

3. Early Morning Waking

And possibly the worst of the signs . . . sudden early morning wakings! If your little one starts waking between 4:00 and 5:00 a.m., take a closer look at the whole schedule before dropping a nap. Early waking alone does not tell you whether they are getting too much daytime sleep.

Sleep Consultant Tip: Don’t rush this transition. If two naps are still working, keep them! If a long morning nap seems to be crowding out the afternoon nap, a small adjustment may help. If your little one’s morning nap is over an hour, try shaving 15 minutes off the morning nap to see if that helps keep both naps for a bit longer. For example, if your child usually sleeps for an hour and a half, wake them at the 1-hour and 15-minute mark for a few days.

If that solves the problem, then great! If your child is coping well but still skipping the afternoon nap, you could try another 15-minute reduction. If they seem more tired or nights worsen, reconsider the adjustment.

What Time Should the One Nap Start?

A nap starting between noon and 1:00 p.m. can be a useful target, but your child’s morning wake time and ability to stay comfortably awake matter too. Treat this as a starting point rather than a deadline.

An early riser may need the nap sooner, especially during the transition. A child who wakes later may manage a later nap. Adjust the timing gradually rather than keeping an exhausted child awake just to reach noon.

Children ages 1–2 generally need 11–14 hours of sleep over 24 hours, including naps. Look at daytime and nighttime sleep together rather than judging the schedule by nap length alone.²

How To Transition From Two Naps to One

Every baby adjusts differently, and the right approach depends on your child’s sleep habits. Two approaches to consider are switching directly or moving the morning nap gradually.

Switch Directly to One Nap

If your child consistently skips the morning nap but still takes the afternoon nap, a direct switch may work. Stop offering the morning nap and offer one midday nap, adjusting the timing to how your child is coping.

Move the Morning Nap Gradually

Use the slow and steady approach if your child is taking the morning nap and skipping the afternoon nap. Begin pushing their morning nap later by 15–30 minutes every couple of days toward a midday nap. How long this takes depends on your starting schedule and how your child responds. Give them time to adjust rather than expecting the new routine to settle within a fixed number of days.

A short nap can happen while your child adjusts to the new schedule. If they wake content, you can give them a brief opportunity to settle again. If they are upset or clearly finished sleeping, respond to their needs rather than extending crib time just to meet a schedule.

After a short nap, consider bedtime about 30–60 minutes earlier than usual, depending on how tired your child seems.

If sleep problems persist or affect your child’s daytime behavior, speak with their pediatrician. Snoring or trouble breathing during sleep also deserves medical attention.¹

Don’t Rush Dropping to One Nap!

If your current nap routine is still working, keep it! Even if your child is in the usual age range, there is no need to change a schedule that is working for them. Look for a consistent pattern, and adjust the timing based on how they sleep and how they feel during the day.
