6 month old sleep schedule

Six months is the transition month. Some babies are still on three naps, some have dropped to two, and most flip back and forth for weeks.

Most 6 month olds land on 12 to 15 hours of sleep across 24 hours, 2 to 3 naps, and wake windows of roughly 2 to 3 hours. Shortest window first thing in the morning, longest before bed.

A day that actually works

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 6 months

Do not force the drop. Let the third nap fall away when it consistently refuses to happen, usually somewhere between 6 and 8 months.

By 6 months tired cues and hungry cues start to look different enough to tell apart, which is the point where a log stops being guesswork and starts being data. 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 6 months

Six months is often when night sleep consolidates properly, though teething and the start of solids both disrupt it. Expect a couple of unsettled weeks around each.

Two babies dropping naps at different times

Twins rarely drop the third nap in the same week. Running one baby on two naps and the other on three for a fortnight is normal and not worth fighting.

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

The 6 month trap is dropping the third nap too early because it is getting hard to fit in. A baby who is not ready ends up overtired by 5pm, and an overtired baby sleeps worse at night, not better.

What changes at 7 months

Solids usually start around now, which shifts feed timing but should not change sleep timing much.

Where the app fits

What helps at this age is a record, not more advice. Multibaby lets you tell whether an early waking is hunger from a new solids routine or simply too much day sleep, because you have both logged in the same place. The wake window calculator will do the arithmetic for a single nap if you just need the next one.
