The sleep of a 10-month-old baby

Ten months is the month of false signals. Your baby refuses the morning nap three days running, you conclude they are moving to one nap, and the following week is a disaster.

The move to a single nap usually happens between fourteen and eighteen months. At ten months, a nap refusal almost always comes from something else: a morning awake window that has become too short, a motor milestone in progress, or simply a bad day.

The right answer at ten months is to lengthen the first awake window by fifteen to thirty minutes — not to drop a nap.

The key point at this age

Why dropping a nap too early backfires

A child short on daytime sleep does not get longer nights. They get more broken ones: more wakings, earlier wakings, harder falling asleep. It is counter-intuitive and well documented. Before twelve months, sleep debt degrades nights instead of consolidating them.

    The timer: when can I put them down?

    Start it the second they fall asleep in your arms.

    --:--before putting them down

    While you wait, keep them against you and try not to move. The countdown will tell you when their sleep is deep enough for the transfer.

    Keep this tab open. The timer stays accurate even if the screen turns off.

    A steady rhythm, unsettled by movement

    Two solid naps and long nights. The main disruptor is no longer sleep itself, but everything your baby is learning to do during the day.

    • Standing up, walking, first words: every new skill gets replayed at night for a few days.
    • The morning nap starts to shorten, the first sign of the move to a single nap.
    • Bedtime often settles between 7 and 8.30 p.m., about three and a half hours after the end of the last nap.
    • Waking before 6 a.m. almost always comes from a bedtime that is too late, not too early.

    The classic trap

    Do not drop the morning nap too soon. Before twelve months, accumulated tiredness degrades nights rather than improving them.

    Falling asleep alone at this age

    ✓ Possible

    Put down awake after their routine, they fall asleep alone. On evenings after a new skill, they will spend a quarter of an hour practising standing up in the cot first.

    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

    My ten-month-old no longer wants the morning nap — what do I do?

    Shift it rather than drop it. Lengthen the morning awake window by fifteen to thirty minutes and watch over a week. If the refusal lasts more than two weeks running, only then consider the transition, with an earlier bedtime.

    How long an awake window at 10 months?

    Three to four hours between sleeps, with the last awake window before bedtime often close to four hours.

    My ten-month-old wakes up crying for no reason — why?

    At this age, separation anxiety, a recent motor milestone or a bedtime that is too late explain the vast majority of cases. If the wakings come with regular snoring, breathing pauses or unusual daytime sleepiness, speak to your GP.
