The sleep of a 7-month-old baby

Seven months is often a quiet month, wedged between the four-month shift and the separation anxiety still to come. Two naps, nights that hold, a readable rhythm.

The awake window lengthens noticeably: two and a half to three hours between sleeps. That is enough for a proper outing, and it is often the point at which days become easier to organise.

If your baby still wakes a lot at night at this age, it is not a fate — but it is not an emergency either. Look first at how they fall asleep in the evening.

The key point at this age

They start sitting up in the cot at night

Around seven or eight months, many babies pull themselves up in the middle of the night, sit, sometimes stand, and cry because they do not know how to get back down. It is not a performance: they are practising, literally, even half-asleep. It lasts a few nights per motor milestone. Practising the reverse movement during the day — sitting down from standing — shortens the period noticeably.

Two naps, and the wakings return

The rhythm simplifies — two well-established naps — but separation anxiety arrives, and with it a wave of night wakings that has nothing to do with sleep.

The move from three naps to two usually happens between six and nine months, and in fits and starts.
Around eight months they understand you exist even when they cannot see you: a real step forward — and one that wakes them.
Sitting or standing up in the cot at night is common: they are practising, even half-asleep.
Teething disrupts things, but rarely for more than a few nights in a row.

The classic trap

A baby who slept well and starts waking again at eight months has not "lost" what they learned. They are going through a developmental stage, and it settles.

Falling asleep alone at this age

✓ Possible

Falling asleep alone is established for many, but separation anxiety can set it back for a few weeks. That is not a loss of skill, it is a parenthesis.

Put down awake, a child of this age usually takes 10 to 20 minutes to fall asleep. That squirming is normal.

The questions of this age

How long an awake window for a seven-month-old?

Two and a half to three hours between sleeps, a little less in the morning, a little more before bedtime. The last awake window of the day is almost always the longest.

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

Most often between 7 and 8.30 p.m., counting about three hours after the end of the last nap. A bedtime that is too late is the main cause of early waking — the opposite of what you would guess.

My seven-month-old refuses one of their two naps — should I drop it?

Not yet. Before nine or ten months, accumulated tiredness degrades nights rather than improving them. Shift the nap, shorten the awake window before it, and keep both as long as they do not refuse it consistently for two weeks.
