What does a full day of sleep look like at 7 months?

Twelve to 15 hours in total, with 10 to 12 of those at night and 2 to 3 naps holding up the day. The night figure is a total rather than a promise of an unbroken block. The practical building tool is the wake window — 2.5 to 3 hours between sleeps — because it adapts to a day that started early or a nap that came out short. Your pediatrician is the person to ask if the totals never get near the range.

Should a 7-month-old have 2 or 3 naps?

Either is normal, because this is the middle of the transition. Many babies run 2 naps most days and slot in a short third one when the morning started early or a nap was cut short. Rather than committing to a number, decide day by day: if the afternoon nap ends early and your baby would otherwise be awake for more than 3 hours, a brief third nap or an earlier bedtime bridges the gap.

Why does my baby sit up in the crib and cry at night?

Because sitting is a brand new skill, and new motor skills get rehearsed in the dark. Babies often push themselves up, then get stuck or lose interest and object. Lay them back down calmly with minimal talking and light, and give lots of daytime practice at both sitting up and getting down again. It usually settles within a couple of weeks.

What time should a 7-month-old go to bed?

Early evening works for most babies at this age, but the right time is set by the last nap rather than by the clock: count a full wake window forward from when it ends, and let bedtime land where it lands. That is why bedtime can be half an hour earlier one day and half an hour later the next without anything being wrong. On days when naps were short, an earlier bedtime isn't a failure — it's the correction.

Baby sleep schedule at 7 months: two naps, wake windows and bedtime

At 7 months your baby needs 12 to 15 hours of sleep a day, with night sleep now stretching to 10 to 12 hours and 2 to 3 naps covering the rest. Wake windows sit at 2.5 to 3 hours. The range on the naps isn't vagueness — it's the transition, still in progress.

Most 7-month-olds are somewhere between three naps and two. On some days the late-afternoon nap still happens and bedtime lands in the early evening anyway; on others it does not, and bedtime needs to move earlier. Planning for both versions of the day is more useful than deciding which one your baby is.

Wake window

During the 3-to-2 transition the two remaining naps have to grow to carry the load, and they take a few weeks to do it. The most reliable structure is a mid-morning nap and an early-afternoon nap, with the afternoon one ending in time to leave a full wake window before bed. On days when the naps come out short, an earlier bedtime is the tool — the night absorbs what the day did not manage.

Sitting up unaided arrives for many babies this month, and a lot of them practice it in the crib at 2 am. It's a phase, not defiance. Give plenty of daytime floor practice so the skill gets boring, lower the crib mattress if you have not already, and keep night responses short and dull. First teeth also often appear now; expect a day or two of grumpiness, not two weeks of ruined nights.

A sample day

The sample below shows a 2-nap day at 7 months, with wake windows of 2.5 to 3 hours. Take it as an example rather than a rule: if your baby still needs a third nap on some days, shift everything earlier and let bedtime come forward.

Time	What happens
7:00	Wake-up and first feed
9:30	Nap 1 · approx. 75 min
14:00	Nap 2 · approx. 90 min
19:00	Bedtime routine and lights out

A sample day to give you a rough idea — every baby is different. Adjust the times to your child's sleep cues, and talk to your pediatrician about anything that worries you.

Tips for this age

Lower the crib mattress once your baby can sit up, keep putting your baby down on their back, and keep the crib itself empty until 12 months.
If the day feels chaotic mid-transition, a week of nap logs in Lulla will show which nap is doing the heavy lifting and which one is collapsing.
Protect the afternoon nap's end time; finishing too late is the single most common reason a 7-month-old resists an early-evening bedtime.
Practice sitting and getting back down on the floor during the day, so the new skill is less compelling in the middle of the night.
If your baby snores routinely, breathes noisily during sleep or seems to pause, mention it to your pediatrician.
