Nap training teaches your baby to fall asleep independently for daytime sleep, using many of the same principles as nighttime sleep training but with a few key differences. Most babies are ready to start around 5 to 6 months old, once their internal clock has matured enough to produce somewhat predictable daytime sleep patterns. Before that age, naps tend to be erratic, and pushing for structure too early usually leads to frustration for everyone.
When Your Baby Is Ready
In the first three to four months, babies start developing a more typical 24-hour sleep-wake cycle, but short, irregular naps are completely normal during this period. Most babies aren’t ready for a set nap schedule with predictable times until at least 6 months. That said, you can begin laying the groundwork around 4 to 5 months by introducing consistent pre-nap routines and paying attention to your baby’s sleep cues.
Signs your baby may be ready for nap training include: being able to fall asleep at bedtime with minimal help, showing predictable tired cues at roughly the same times each day, and no longer needing a feeding to fall asleep. If nighttime sleep is still very disrupted, it often helps to work on that first, since nighttime sleep tends to consolidate before daytime sleep does.
Get the Timing Right With Wake Windows
The single most important factor in successful nap training is putting your baby down at the right time. Too early and they won’t have enough sleep pressure to fall asleep. Too late and they’ll be overtired and wired. Wake windows, the stretch of awake time between one sleep period and the next, give you a reliable framework.
- 3 to 4 months: 1.25 to 2.5 hours
- 5 to 7 months: 2 to 4 hours
- 7 to 10 months: 2.5 to 4.5 hours
- 10 to 12 months: 3 to 6 hours
These ranges are wide because the first wake window of the day is usually the shortest, and the last one before bedtime is the longest. Start by watching your baby’s sleepy cues (rubbing eyes, yawning, zoning out) and matching them against these ranges. Within a week or two, you’ll notice patterns you can build a schedule around.
Set Up the Right Sleep Environment
Daytime sleep is biologically harder than nighttime sleep because your baby’s body isn’t producing as much of the hormone that drives sleepiness. That means the environment matters even more for naps. Keep the room dark, genuinely dark, not just dimmed. Blackout curtains or shades make a noticeable difference because even small amounts of light signal “awake time” to your baby’s brain.
Keep the room between 68 and 72 degrees Fahrenheit. White noise can help mask household sounds and provide a consistent sleep cue. Place your baby on their back in a crib, bassinet, or portable play yard with a firm, flat mattress and fitted sheet. Nothing else belongs in the sleep space: no blankets, pillows, stuffed animals, or bumpers.
Build a Short Pre-Nap Routine
Your bedtime routine might take 20 to 30 minutes, but a nap routine should be a condensed version, around 5 to 10 minutes. The goal is to signal that sleep is coming without dragging things out so long that your baby misses their window. A simple sequence works well: close the curtains, turn on white noise, change the diaper if needed, read a short book or sing a song, then place your baby in the crib drowsy but awake.
“Drowsy but awake” is the phrase you’ll see everywhere, and it’s the cornerstone of nap training. It means your baby’s eyes are heavy and they’re calm, but they haven’t fully fallen asleep in your arms. The point is to give them the chance to do that last bit of falling asleep on their own, in their crib. This is the skill you’re teaching.
Choosing a Nap Training Method
There’s no single correct method. What matters is consistency. Here are the two most commonly used approaches for naps.
Timed Check-Ins (Ferber Method)
After placing your baby in the crib awake, leave the room. If they cry, wait a short, predetermined interval before going back in, starting with something like 3 minutes. When you check in, keep it brief: one to two minutes maximum. You can pat their back or speak softly, but don’t pick them up or feed them. Leave again and stretch the wait time to 5 minutes, then 8, then 10. On the following day, start with longer intervals. The gradually increasing wait times give your baby space to practice falling asleep while reassuring them you’re still nearby.
Pick Up, Put Down
This approach involves more hands-on comfort. When your baby cries, you pick them up and soothe them until they’re calm but not asleep, then place them back in the crib. You repeat this cycle as many times as needed. It tends to take longer per nap session and can be physically exhausting, but some parents prefer it because they’re never leaving their baby to cry alone. It works best for babies under 7 months or so; older babies often find the repeated picking up and putting down more stimulating than soothing.
Why Naps Are Harder Than Nighttime
If you’ve already sleep trained at bedtime and it went smoothly, you might be surprised that naps feel like starting over. There’s a biological reason. At night, your baby’s body produces a strong hormonal drive toward sleep. During the day, that drive is much weaker, so your baby has to work harder to fall asleep and is more easily disrupted.
Give nap training at least two weeks of consistent effort before deciding it isn’t working. Many babies show real progress by days 5 to 7, but some take longer. The first nap of the day usually responds to training fastest because sleep pressure is highest after a full night. The afternoon nap often takes more time to click into place.
Dealing With Short Naps
A baby’s sleep cycle lasts about 45 to 60 minutes. When a nap ends right at that mark, your baby woke at the natural transition between sleep cycles and couldn’t link into the next one. This is one of the most common frustrations during nap training, and it’s developmentally normal, especially before 6 months.
When your baby wakes after one cycle, you have a few options. You can leave them in the crib for 10 to 15 minutes to see if they resettle on their own. Some babies fuss briefly and drift back to sleep. If they don’t, you can try a brief soothing intervention (gentle patting, shushing) without picking them up. If they’re fully awake and upset after 10 to 15 minutes, call the nap done and adjust the next wake window accordingly, shortening it slightly since they got less sleep.
Short naps often resolve on their own somewhere between 6 and 8 months as your baby’s ability to connect sleep cycles matures. In the meantime, focus your training energy on the act of falling asleep at the start of the nap. That’s the skill that eventually enables longer naps too.
When Nap Schedules Shift
Just when you feel like you’ve figured things out, your baby’s nap schedule will change. Babies typically move from three naps to two somewhere around 7 to 9 months, and from two naps to one around 14 to 18 months.
Signs a nap transition is coming include: resisting one of the naps (usually the last one of the day), skipping naps entirely, taking shorter naps than usual, or suddenly waking early in the morning or in the middle of the night. If your toddler is regularly getting less than 10 hours of nighttime sleep on a two-nap schedule, shifting to one nap often helps lengthen overnight sleep.
Nap transitions usually take one to three weeks to fully settle. During that messy middle period, you might alternate between the old and new schedule depending on how your baby slept the night before. An earlier bedtime on days when a nap is missed or short helps prevent a spiral of overtiredness.
What a Typical Training Day Looks Like
For a 6-month-old on three naps, a training day might look something like this. Your baby wakes around 7:00 a.m. After about two hours, you start your short nap routine and place them in the crib by 9:00 a.m. They fuss for 10 to 15 minutes (you do your check-ins or chosen method), then fall asleep. They sleep 45 minutes to an hour and a half. You repeat the process for the second nap about two to three hours later. The third nap, if needed, is often a short “bridge” nap of 20 to 30 minutes to get them to bedtime without being overtired. Many parents are more flexible with this third nap, allowing it in a stroller or carrier since it’s temporary and will drop within a few months anyway.
On early training days, some naps will go well and others will be a disaster. That’s normal. The morning nap almost always improves first. Track what’s happening so you can spot patterns: maybe your baby does better with a slightly longer wake window, or maybe the room isn’t dark enough in the afternoon when the sun hits that side of the house. Small adjustments compound over time.
