11 month old wake windows and the fake one nap phase

Many 11 month olds start refusing the morning nap for a week or two, then take it again as if nothing happened.

An 11 month old is often awake 3 to 4 hours between sleeps, still on 2 naps a day of about 1 to 1.5 hours each. Total sleep usually falls around 12 to 16 hours, with about 9 to 12 hours at night, often with wakes.

Eleven months is where the morning nap starts getting tested. Plenty of babies skip it for a few days, sleep badly that night, then go back to two naps without warning. Wake windows are practitioner rules of thumb rather than guidance published by the AAP or NHS, so use 3 to 4 hours as a frame and let what you see in your baby decide.

What changes at 11 months

  • The awake stretch is still 3 to 4 hours, but many babies now hold the top of that range comfortably where a month ago they could not.
  • Morning nap resistance appears in a lot of 11 month olds, and it usually passes rather than marking a real transition.
  • First steps, first words and a great deal of problem solving arrive around now, and new skills often surface at the edge of sleep.
  • Naps stay at 2 a day of about 1 to 1.5 hours each, though the two may become less evenly matched.

What tired looks like right now

  • Slowing down mid activity and coming to lean on you, then heading straight back off again.
  • Repeating one action over and over, like opening and shutting a drawer, instead of moving between toys.
  • Frustration spikes over small things, such as a lid that will not fit, which often shows up before eye rubbing at this age.
  • Throwing food from the high chair rather than eating it, which can read as tired more than fussy.

When it goes sideways

They refuse the morning nap entirely for several days in a row

This is common enough at 11 months to have a nickname among sleep practitioners: the false one nap phase. A baby holds out on the morning nap, copes for a few days, then falls apart. Most are not ready to drop it, since 2 naps typically hold until somewhere between 13 and 18 months. Offering the nap slightly later, and holding the routine for a couple of weeks, usually brings it back.

Bedtime has crept later and later

When the morning nap gets skipped or cut short, the rest of the day compresses and the last wake window often stretches past 4 hours. That tends to push bedtime later while making settling harder, not easier. On days when the morning nap is missed, many families bring the second nap forward and then bring bedtime forward too, rather than holding the usual time.

Night wakes have come back after months of sleeping through

A stretch of broken nights around 11 months often lines up with the morning nap being skipped, a burst of new skills, or separation awareness sharpening. Overtiredness from a missed nap is the most common thread. Keeping the day as close to 2 naps as possible, and resisting the urge to make bedtime later, usually helps more than changing anything at night. If wakes come with fever or pain, speak to your doctor.

Questions parents ask at this age

How long can an 11 month old stay awake before their first nap?
Many 11 month olds manage 3 to 4 hours before the first nap, and this window is often the shortest of the day. Some babies who have just started walking hold it longer. Wake windows are heuristics used by sleep practitioners rather than official guidance, so the way your baby settles matters more than hitting an exact minute.
Is it normal for an 11 month old to skip the morning nap?
Very normal. Morning nap refusal shows up in a lot of 11 month olds and often lasts a week or two. Many babies who skip it still need it, which shows up as a hard afternoon, an early bedtime crash or a 5am start. Most go back to 2 naps if the offer keeps being made.
Should I drop to one nap if my 11 month old keeps refusing?
Usually not yet. The genuine move to one nap tends to happen somewhere between 13 and 18 months, and 11 months is early for it. Refusal that lasts less than about two weeks, with tired afternoons in between, generally points to a phase rather than a transition. Holding two naps while the refusal plays out is the common approach.
How do I get the morning nap back after a few days of refusal?
Keep offering it at the same point in the routine, and try nudging it slightly later so the wake window sits nearer 4 hours. A darker room and a shorter wind down often help, since resistance at this age is frequently about not wanting to stop rather than not being tired. Many babies take it again within one to two weeks.
What time should the second nap start for an 11 month old?
Rather than a fixed clock time, most families count 3 to 4 hours from the end of the first nap. If the first nap was short, the second often needs to come nearer the lower end. Keeping the second nap finished with enough of the day left protects bedtime, which is usually the piece that suffers first.
Why is my 11 month old suddenly hard to settle at bedtime?
Settling trouble at 11 months often comes from a day that lost its shape. A missed morning nap, a very long last wake window or a burst of new movement can all leave a baby wired at bedtime. Separation awareness is also strong around now, so goodnights may simply take longer than they did a month ago.
How much daytime sleep does an 11 month old need?
Daytime sleep at 11 months usually comes from 2 naps of about 1 to 1.5 hours each. Across the full 24 hours, 12 to 16 hours is typical, and night sleep is about 9 to 12 hours, often with wakes. Some days will land short, and one light day rarely matters on its own.
What should I do if my 11 month old only naps once that day?
One nap days happen. Most families shorten the last wake window and bring bedtime forward rather than holding the usual time, since a baby running on one nap is usually short on sleep by late afternoon. An earlier night often prevents the 5am wake that would otherwise follow. The next day generally goes back to 2 naps.
Is one long nap better than two short ones at 11 months?
At this age two naps usually serve a baby better, even if one of them is short. Splitting sleep keeps the wake windows inside 3 to 4 hours, which is what most 11 month olds can comfortably manage. A single long nap tends to leave a very long stretch before bed, and that stretch is where overtiredness builds.
