Most 11-month-olds need about 13.5 hours of total sleep per day, split between 11 to 12 hours at night and 2 to 3 hours across two daytime naps. If your baby is fighting bedtime, waking frequently, or refusing naps, you’re not alone. At 12 months, roughly 28% of babies still aren’t sleeping six consecutive hours at night, and over 43% aren’t managing eight hours straight. The good news: this is a predictable rough patch, and a few targeted changes can make a real difference.
Why 11-Month-Olds Struggle With Sleep
Your baby’s brain is doing an enormous amount of work right now. They’re learning to stand, cruise along furniture, and possibly take first steps. Many are starting to imitate sounds, say “mama” or “dada,” and grasp the concept that you still exist when you leave the room. That last one, called object permanence, is directly tied to separation anxiety, which tends to peak around 9 to 12 months. Your baby may cry harder at bedtime simply because they now understand you’re leaving.
All of these milestones compete with sleep. A baby who just figured out how to pull to standing may pop up in the crib over and over, too excited to lie down. Cognitive leaps can make their brain buzz at naptime. This is sometimes called the “11-month sleep regression,” though it’s really a sign of healthy development temporarily colliding with sleep.
Set the Right Wake Windows
At 11 months, most babies do best with about 3 to 3.75 hours of awake time between sleep periods. If the gap is too short, they won’t be tired enough to fall asleep easily. Too long, and they become overtired and wired. A schedule that works for many families looks something like this:
- Wake up: 6:30 a.m.
- First nap: 9:30 to 10:45 a.m. (about 1.25 hours)
- Second nap: 2:15 to 3:30 p.m. (about 1.25 hours)
- Bedtime routine starts: 6:30 p.m.
- Asleep: 7:15 p.m.
The wake window before bedtime is usually the longest one, around 3.5 to 3.75 hours. Each nap should ideally last at least 60 minutes. If your baby is consistently taking very short naps or refusing one entirely, it’s tempting to assume they’re ready for one nap. Resist that urge. The typical transition to one nap happens between 13 and 18 months. Some daycares push it as early as 11 months, but at home, sticking with two naps usually leads to better nighttime sleep at this age.
Build a Predictable Bedtime Routine
A short, consistent sequence of events before bed signals to your baby that sleep is coming. This doesn’t need to be elaborate. Bath, pajamas, a book, a song, and into the crib works well. The key is doing the same steps in the same order every night. Consistency helps manage separation anxiety too, because your baby starts to learn the pattern and what to expect at the end of it.
When it’s time to say goodnight, keep it brief and warm. Give affection, say your goodnight phrase, and leave. Lingering at the crib when your baby is crying actually extends the anxiety rather than soothing it. A quick, loving goodbye repeated the same way each night builds trust over time.
Teach Your Baby to Fall Asleep Independently
The single biggest factor in whether a baby sleeps through the night is whether they can fall asleep on their own at the start of the night. Babies wake briefly between sleep cycles, just like adults do. If they fell asleep being rocked or fed, they’ll need that same help to get back to sleep at 1 a.m. and 4 a.m. If they fell asleep in the crib on their own, they’re far more likely to roll over and drift back off without calling for you.
One widely used approach is graduated extinction, sometimes called the Ferber method. You go through your bedtime routine, put your baby down awake, say goodnight, and leave. If they cry, you return briefly to pat them and offer reassurance, then leave again. Over the first few nights, you go back fairly quickly. After that, you gradually stretch the intervals before checking in, giving your baby more time to figure out how to settle themselves. Most families see significant improvement within a week.
If that feels too intense, you can try staying in the room initially. Sit in a chair near the crib while your baby falls asleep, offering occasional verbal reassurance but not picking them up. Over several nights, move the chair farther from the crib until you’re outside the door. This takes longer but some parents find it more comfortable.
Handle Night Wakings and Feeding
If your baby is formula-fed, they likely don’t need calories overnight at this age. Formula digests slowly enough that a baby over 6 months who eats well during the day is almost certainly waking from habit, not hunger. For breastfed babies, the picture is slightly different. Most experts suggest waiting until around 12 months to fully night wean from breastfeeding, since many breastfed babies are still getting meaningful nutrition from those feeds. At 11 months, you’re close to that threshold, and you can start by gradually reducing the length of nighttime feeds to ease the transition.
Solid food intake during the day matters here. Research from King’s College London found that babies who ate solids well during the day slept longer at night and woke less frequently. At 11 months, your baby should be eating three meals of solid food plus breast milk or formula. If daytime eating has been light, increasing it can genuinely help nighttime sleep. Think protein and fat-rich foods at dinner: avocado, full-fat yogurt, scrambled eggs, or nut butters spread thin on soft bread.
Manage Separation Anxiety at Bedtime
Separation anxiety is one of the trickiest parts of this age because it can undo sleep skills your baby already had. A baby who was sleeping through the night at 8 months may suddenly scream when you leave the room at 11 months. This is developmentally normal and temporary.
During the day, practice short separations. Leave the room for a minute, come back cheerfully. Let a grandparent or trusted friend watch your baby while you step out for an errand. These small experiences teach your baby that you always come back. At bedtime, avoid sneaking out of the room after they fall asleep. If they wake and discover you left without warning, it reinforces the fear. A clear, consistent goodbye is better than a secret exit, even if it causes a few tears in the moment.
Make the Crib Safe and Boring
Once your baby can pull to standing, lower the crib mattress to its lowest setting if you haven’t already. The top of the crib rail should be well above your baby’s chest when they’re standing. Keep the crib free of loose blankets, pillows, stuffed animals, and bumper pads. A firm, flat mattress with a fitted sheet is all that belongs in there. If the room is cold, use a sleep sack instead of a blanket.
Darkness helps too. A pitch-dark room signals nighttime to your baby’s brain. If you use a nightlight, keep it dim and warm-toned, away from the crib. White noise can mask household sounds and create a consistent sleep cue, but keep the volume moderate and the machine across the room rather than right next to your baby’s head.
When Your Baby Stands Up in the Crib
This is one of the most common 11-month sleep problems. Your baby pulls to standing, gets stuck, and cries because they haven’t figured out how to get back down. During the day, practice sitting down from standing by guiding their hands down the crib rail or the edge of the couch. The more they practice this skill while awake, the faster they’ll use it at night.
At bedtime, if your baby stands up, lay them back down once or twice calmly and without fanfare. If they keep popping up, it’s fine to leave the room and let them figure it out. They won’t sleep standing up forever. Most babies work this out within a few nights once they have the motor skill to lower themselves down.
