Eleven months looks like the two-nap day, with a baby who is increasingly opinionated about it.
Most 11 month olds land on 11 to 14 hours of sleep across 24 hours, 2 naps, and wake windows of roughly 3 to 4 hours. Shortest window first thing in the morning, longest before bed.
A day that actually works
| Time | What happens | Wake window |
|---|---|---|
| 7:00 | Wake and first feed | - |
| 10:15 | Nap 1 | 195 min |
| 11:45 | Wake, feed | - |
| 15:30 | Nap 2 | 225 min |
| 17:00 | Wake, feed | - |
| 21:00 | Bedtime routine, then bed | 240 min |
The times are a sketch. The wake windows are the part worth holding onto, because they are what stops a baby arriving at a nap already overtired.
The thing to get right at 11 months
Nap refusal at 11 months is usually a wake window that is too short, not a baby ready for one nap. Lengthen the morning window before dropping anything.
At 11 months the clearest signal is the evening. A baby who is cheerful at 6pm and hysterical at 6:20 was overtired well before the meltdown. Watching the clock beats waiting for cues at every age under one, and a baby who is past the window fights the nap you were trying to give them.
Night sleep at 11 months
Eleven month night sleep is usually stable. If it is not, look at the last wake window of the day before anything else; too short a gap before bed is the most common cause.
Two babies through the first birthday
Keep both babies on two naps through the first birthday if you can. Twins who drop to one nap at 11 months usually end up overtired by 4pm, and an overtired pair is a worse evening than a short second nap.
Everything above applies to each baby on their own, which is the problem: two babies on separate schedules means nobody is ever asleep at the same time. One decision does most of the work, and it is the morning. Wake both babies within about half an hour of each other and the rest of the day follows. During the day the rule flips, though: let a nap finish rather than rousing the second baby, then shorten the next wake window for whoever is running ahead.
If your twins were born early, use corrected age for all of this. A baby born eight weeks premature follows a schedule about eight weeks behind their calendar age, and the smaller twin often needs slightly shorter windows than their sibling.
Where it usually goes wrong
Skipping the morning nap for a week does not mean a baby is ready for one nap. Most are not until 14 to 18 months, and moving early produces a reliably terrible 4pm.
What changes after the first birthday
Walking, and the sleep disruption that comes with it, is usually still a month or two away.
Where the app fits
What helps at this age is a record, not more advice. Multibaby lets you hold the line on two naps with evidence rather than instinct, by seeing what actually happened the last time a nap was skipped. The wake window calculator will do the arithmetic for a single nap if you just need the next one.
