Baby sleep at 11 months: what is normal, what is tricky, and when to call the pediatrician

How things are shifting at 11 months

Your baby is nearing the CDC’s 1-year milestones: pulling up to stand, cruising along furniture, waving bye-bye, understanding “no”, and playing games such as pat-a-cake. All that new ability brings plenty of new reasons to stay awake.

Separation anxiety tends to be close to its peak; the AAP puts the typical peak between 10 and 18 months.

The need for sleep does not drop sharply at the birthday. In a review of studies, babies from 9 months averaged 12.6 hours per 24 hours and babies from 12 months averaged 12.9 hours, so total sleep should look much the same for the next few months.

One nap or two	Probably a phase	Probably genuine readiness
Age	Younger than 12 months	12 to 18 months, the window when most babies switch (review of studies)
Pattern	Skips a nap for a few days, then goes back to taking it	Skips the second nap on most days for two weeks or longer
Mood	Grumpy by late afternoon	Manages well on one nap all the way to bedtime
Nights	More night waking or early waking	Nights hold steady

At 11 months, nap strikes and early waking frequently fuel each other, and the fix that helps one baby can make things worse for another. Actually Sleeping identifies which pattern your baby fits and writes a plan for it, with Dr. Sam checking in 1:1 with you each day.

The age row is drawn from a systematic review of napping studies. The remaining rows are a rule of thumb that many families find helpful, not a finding from a study.

What parents struggle with most

Nap strikes. Babies who move to one nap too soon often begin waking at night or very early in the morning.
Bedtime battles. Greater awareness brings greater protest.
Illness. Every cold can mean rough nights, and the extra help offered while a baby is unwell can last longer than the illness itself.
Worrying about the first birthday switch in daycare rooms, which often move children to one nap at a fixed age.

Keeping sleep safe at 11 months

The AAP’s safe sleep recommendations apply to babies up to 1 year. Until then, keep the crib empty and begin every sleep on the back.
Keep bottles out of bed. As part of its advice on preventing tooth decay, the AAP recommends against putting a baby to bed with a bottle.
Set the mattress to its lowest position. Compare the rail height with your baby as they grow.
Position the crib away from windows and blind cords, and secure nearby furniture to the wall.

Feeds overnight

At the 12-month check, ask your pediatrician about switching to whole milk. Your custom plan sets how night feeds are handled according to your baby’s age.

When to check in with the pediatrician

Snoring on most nights, pauses in breathing, or daytime sleepiness that seems like too much.
Night waking along with fever, ear pulling, or crying that sounds like pain.
As 12 months nears, your baby is not yet pulling to stand, babbling, or using gestures such as waving.
Repeated night terrors or screaming episodes.

Common questions

Should my 11 month old move to one nap?

Most likely not yet. According to a systematic review of napping studies, the main move away from two naps a day comes between 12 and 18 months. Brief stretches of nap refusal are common at 11 months, and cutting a nap early often leads to night or early waking.

Is a blanket in the crib okay for an 11 month old?

The AAP’s safe sleep recommendations run until the first birthday and call for a crib free of blankets, pillows, bumpers and soft toys. Choose a wearable blanket or sleep sack instead. Check with your pediatrician about changes after age 1.

How many hours of sleep does an 11 month old need?

For babies 4 to 12 months, the AASM recommends 12 to 16 hours per 24 hours, naps included. A review of studies found that babies from 9 months averaged roughly 12.6 hours, with healthy babies falling on both sides of that figure.
