Most 11-month-olds need 2 to 3 hours of daytime sleep, split across two naps. Combined with 11 to 12 hours of nighttime sleep, that puts total sleep around 13.5 hours per day. The American Academy of Pediatrics recommends 12 to 16 hours of total sleep (including naps) for babies ages 4 to 12 months.
How Long Each Nap Should Be
At 11 months, two naps per day is still the norm. Those two naps should add up to roughly 2 to 3 hours total. The exact split varies by baby, but a common pattern is a longer morning nap of about 1 to 1.5 hours and a slightly shorter afternoon nap of 45 minutes to 1 hour. Some babies split the time more evenly.
If your baby’s naps consistently add up to less than 2 hours, nighttime sleep may suffer because overtiredness makes it harder to fall asleep and stay asleep. On the other end, naps totaling more than 3 hours can push bedtime too late or lead to nighttime waking.
Why Some Naps Are Only 30 Minutes
Babies have shorter sleep cycles than adults, and when they briefly wake between cycles, they don’t always know how to fall back asleep on their own. That’s why you might see your 11-month-old pop awake after exactly 30 minutes looking wide-eyed and alert. A single sleep cycle ended, and they couldn’t bridge the gap to the next one.
Occasional short naps are normal. But if every nap is 30 minutes or less, it’s worth looking at the environment (dark room, white noise, consistent routine) and whether your baby is going down too drowsy or not drowsy enough. Babies who are put down already deeply sleepy sometimes struggle more with those between-cycle wake-ups because they don’t practice the skill of drifting off independently.
Wake Windows at 11 Months
Wake windows, the stretches of awake time between sleep periods, are just as important as nap length. At 11 months, most babies handle about 3 to 3.5 hours of awake time before their first nap, 3 to 3.5 hours between the first and second nap, and 3.5 to 4 hours before bedtime. That last window is typically the longest.
If wake windows are too short, your baby won’t have built up enough sleep pressure to nap well. Too long, and they tip into overtiredness, which paradoxically makes sleep harder, not easier. Watch for sleepy cues like eye rubbing, zoning out, or fussiness, but use the clock as a guide too, since some babies don’t show obvious signs until they’re already overtired.
A Sample Schedule That Works
Here’s one way a day might look for an 11-month-old waking at 7:00 AM:
- 7:00 AM: Wake up
- 10:00 AM to 11:15 AM: First nap (about 1.25 hours)
- 2:30 PM to 3:30 PM: Second nap (about 1 hour)
- 7:30 PM: Bedtime
If the afternoon nap ends around 3:30 PM, a bedtime near 7:30 PM works well for most babies. Try to avoid letting that second nap run past 4:00 PM, since a late afternoon nap can push bedtime too late and create a cascade of early morning waking.
Your baby’s schedule doesn’t need to match this exactly. The key numbers to protect are 2 to 3 hours of total daytime sleep and at least 10 hours overnight (with 11 to 12 being the sweet spot).
Don’t Drop to One Nap Yet
Around 11 months, many babies start resisting their second nap, skipping it entirely, or taking shorter naps than usual. It’s tempting to read this as a sign they’re ready for one nap. They’re almost certainly not. Most children aren’t ready for a consistent one-nap schedule until at least 14 months, and many don’t fully transition until 14 to 18 months.
What looks like nap refusal at 11 months is more often a developmental leap. Babies this age are pulling to stand, cruising, possibly taking first steps, and understanding more language than ever. Their brains are buzzing, and lying still in a dark room feels like a terrible idea to them. This phase usually passes within a few weeks if you keep offering both naps.
Dropping a nap too early leads to significant overtiredness, which can cause increased fussiness, nighttime waking, and early morning wake-ups. If your baby occasionally skips the second nap, move bedtime earlier that night to compensate rather than restructuring the whole schedule.
Signs Your Baby Needs a Schedule Adjustment
Even within the normal range, small tweaks can make a big difference. Consider adjusting the schedule if your baby is consistently taking more than 20 minutes to fall asleep at naptime (wake windows may be too short), waking overnight after previously sleeping through (total daytime sleep may be too high or too low), or waking before 6:00 AM most mornings (bedtime may be too late, or the last nap may be running too long).
If your baby is regularly getting less than 10 hours of nighttime sleep on a two-nap schedule, that’s another signal. Sometimes capping daytime naps at 2.5 hours or gently shortening the afternoon nap frees up more sleep drive for the night. Make changes gradually, shifting nap times or lengths by 15 minutes every few days, so your baby can adjust without becoming overtired in the process.
