Most babies follow a two-nap schedule from roughly 8 or 9 months old until somewhere between 14 and 18 months, meaning the two-nap phase typically lasts about 5 to 9 months. That’s a wide range because every child’s sleep needs develop on their own timeline, but it gives you a reliable window to plan around.
When the Two-Nap Schedule Starts
Babies don’t begin life on two naps. Newborns sleep in short bursts throughout the day, gradually consolidating into three distinct naps by around four to six months. The shift from three naps to two happens when that late-afternoon catnap stops working. Most babies are ready to fully drop the third nap by 8 to 9 months, though it’s common for 6- and 7-month-olds to start fighting it. Once that third nap disappears, you’re in two-nap territory: one in the midmorning and one around midday.
What a Typical Two-Nap Day Looks Like
During the peak of the two-nap phase (roughly 9 to 12 months), babies generally stay awake for 2.5 to 3.5 hours between sleep periods. By 11 to 12 months, those awake stretches lengthen to about 3 to 4 hours. A common pattern is a morning nap starting around 9:00 or 9:30 a.m. and an afternoon nap beginning around 1:00 or 2:00 p.m., with bedtime falling somewhere between 7:00 and 8:00 p.m.
The AAP notes that from four months through the rest of the first year, most infants need at least two naps. Total sleep for a 12- to 24-month-old should land between 11 and 14 hours in a full day, including naps. If your child’s schedule consistently hits that range with two naps, the schedule is working.
When Babies Drop to One Nap
The morning nap is the one that eventually fades. According to the AAP, a small number of children begin tapering the morning nap around 10 to 12 months. By 15 months, about half of all children take only one nap a day, typically in the afternoon. By 24 months, nearly all children have made the switch.
Most children aren’t truly ready for a consistent one-nap schedule until at least 14 months. Daycare settings often push the transition earlier, around 12 months, for logistical reasons. If your child seems to handle that fine and still sleeps well at night, it’s not a problem. But if they’re melting down by 4:00 p.m. or waking frequently overnight, they may have been moved too soon.
Signs Your Baby Is Ready to Drop a Nap
Look for a cluster of these behaviors showing up consistently for at least one to two weeks:
- Fighting nap time. Your child regularly protests or refuses one of their naps, especially the morning one.
- Short naps. Naps that used to last over an hour shrink to 30 or 40 minutes.
- Late bedtimes. Fitting two naps into the day pushes bedtime so late that nighttime sleep suffers.
- Night wakings or early mornings. Too much daytime sleep starts fragmenting their overnight stretch.
The key is consistency. A few off days don’t mean it’s time to restructure the whole schedule. You want to see these patterns holding steady over at least a couple of weeks before making a change.
The 12-Month Sleep Regression Trap
Many parents get tripped up around 10 to 12 months, when babies go through a well-known sleep regression that looks a lot like readiness to drop a nap. Your baby might suddenly refuse the second nap, fight bedtime, or wake up at 5:00 a.m. for a few days in a row. It feels like a signal to change something.
It usually isn’t. This regression is driven by developmental changes, not a reduced need for sleep. Babies at this age are learning to stand, cruise, and sometimes walk. They’re also beginning to assert preferences, and “not in the mood for sleep” is a popular one. The regression typically passes within a few weeks. If you drop to one nap too early in response, you often end up with an overtired baby who sleeps worse, not better.
A good rule of thumb: if your child is under 13 months and suddenly refusing a nap, wait it out. Offer a quiet rest period during the usual nap time even if they don’t sleep. Most babies settle back into two naps once the regression runs its course.
How Long the Transition Takes
Once you’ve confirmed the signs and decided to move to one nap, expect the adjustment period to take a few weeks. Early in the transition, your child may seem tired in the late morning, and that’s normal. You can gradually push the single nap later, shifting it by 15 to 30 minutes every few days until it lands around 12:30 or 1:00 p.m. An earlier bedtime (sometimes as early as 6:30 p.m.) helps bridge the gap while their body clock catches up.
Some families find that an “alternating” approach works during the messy middle period: offering two naps on days when the child clearly needs them and one nap on days when they’re managing well. This flexibility is fine and doesn’t set your child back. The goal is adequate total sleep, not a rigid schedule.
