An 11-month-old needs 12 to 16 hours of total sleep per 24-hour period, including naps. That typically breaks down into 9 to 12 hours of nighttime sleep plus two daytime naps. Where your baby falls in that range depends on their individual temperament, how long their naps run, and how well they sleep at night.
Nighttime and Daytime Sleep Breakdown
Most of your baby’s sleep should happen at night in one long stretch of 9 to 12 hours. Some 11-month-olds sleep through without waking, while others still wake once or twice. Both patterns are normal at this age.
During the day, your baby will likely take two naps. Individual naps can range from 30 minutes to 2 hours, and the total daytime sleep usually adds up to 2 to 3 hours. A baby who takes shorter naps may need a slightly earlier bedtime to hit that 12-to-16-hour total, while a baby who naps well may do fine with a later one.
Wake Windows Between Sleeps
At 11 months, most babies can handle 3 to 4 hours of awake time between sleep periods. The first wake window of the day is usually the shortest, around 3 hours from morning wakeup to the first nap. The gap between the two naps stretches to about 3 to 3.5 hours, and the longest stretch comes at the end of the day: 3.5 to 4 hours between the second nap and bedtime.
These windows matter because timing sleep correctly prevents overtiredness. When a baby stays awake too long, their body releases stress hormones that make it harder, not easier, to fall asleep. You’ll see the signs: clinginess, crying, fussiness with food, increased hyperactivity, clumsiness, or sudden boredom with toys they normally enjoy. If your baby regularly fights bedtime or takes a long time to settle, the wake window before bed may be too long (or occasionally too short).
Is It Time to Drop to One Nap?
Around 11 months, some babies start resisting their second nap, and parents wonder if it’s time to switch to one nap a day. In most cases, the answer is no. The typical age for that transition is 18 to 24 months. What looks like a nap refusal at 11 months is more often a temporary disruption caused by developmental changes rather than a permanent shift in sleep needs.
If your baby skips the second nap occasionally but is clearly tired and cranky by late afternoon, they still need two naps. Keep offering the opportunity even if they don’t always take it. Dropping a nap too early usually backfires: the baby becomes chronically overtired, which leads to worse nighttime sleep, not better.
Why Sleep Falls Apart Around This Age
Many parents notice sleep getting rockier as their baby approaches 12 months, and there are real developmental reasons for it. Babies at this age are learning to stand, cruise along furniture, and possibly take first steps. They’re also showing more emotional complexity, increased communication, and stronger social awareness. All of that mental and physical growth can make them restless, overstimulated, and harder to settle.
Separation anxiety is one of the biggest sleep disruptors at this stage. Your baby now understands that you exist when you leave the room, and they don’t love it. This can make falling asleep alone at bedtime feel harder, and it can cause more frequent night wakings as your baby looks for reassurance. This phase is temporary, even though it doesn’t feel like it in the middle of the night. Most babies work through it within a few weeks.
Night Feedings at 11 Months
Whether your baby still needs to eat overnight depends partly on how they’re fed. Formula-fed babies over 6 months old are unlikely to wake from genuine hunger, since formula digests slowly and they’re getting plenty of calories during the day. If a formula-fed 11-month-old wakes at night, it’s more often habit or comfort-seeking than nutritional need.
For breastfed babies, the picture is a bit different. Night feeds before 12 months still play a role in maintaining milk supply, so most experts suggest waiting until at least 12 months to actively night-wean a breastfed baby. That said, many breastfed 11-month-olds are naturally down to one overnight feed or none at all. If your baby is growing well and eating solid foods consistently during the day, a single night feed at this age is fine but not strictly necessary from a nutritional standpoint.
What a Typical Day Looks Like
Every baby is different, but a common rhythm for an 11-month-old looks something like this:
- Morning wakeup: 6:00 to 7:00 a.m.
- First nap: about 3 hours after waking, lasting 1 to 1.5 hours
- Second nap: about 3 to 3.5 hours after the first nap ends, lasting 30 minutes to 1.5 hours
- Bedtime: 3.5 to 4 hours after the second nap ends, usually between 7:00 and 8:00 p.m.
If your baby’s naps are on the shorter side, you may need to shift bedtime earlier to keep the total sleep in the 12-to-16-hour range. A bedtime of 6:30 p.m. might feel early, but for a baby who only napped 45 minutes all day, it can be the difference between an easy settle and a meltdown.
Signs Your Baby Is Getting Enough Sleep
The 12-to-16-hour guideline is a range for a reason. Some babies genuinely thrive on 12 hours, while others need closer to 15 or 16. Rather than fixating on hitting an exact number, look at how your baby behaves during the day. A well-rested 11-month-old is generally alert and curious during wake windows, able to play independently for short stretches, and settles to sleep within about 15 to 20 minutes at nap time and bedtime.
A baby who is consistently falling short on sleep tends to be irritable, clingy, or wired throughout the day. They may have trouble with meals, cry more easily, or paradoxically seem to have more energy rather than less. If that pattern is ongoing, experimenting with slightly earlier nap times or an earlier bedtime is a reasonable first step.
