When to Drop to One Nap: Why 11 Months Is Usually Too Early

Two naps is still the normal picture at 11 months

Between 4 and 12 months, most babies take two to three daytime naps, and somewhere in that stretch they settle from three naps into two longer ones. At 8 to 12 months a baby will likely still take two naps a day, inside a total of 12 to 16 hours of sleep, with a long block of 9 to 12 hours at night. Nap length varies enormously between babies: some sleep 30 minutes, others up to two hours.

The move to one nap mostly belongs to the second year. Most toddlers condense their two naps into one afternoon nap at around 18 months, sometimes sooner. The Canadian Paediatric Society describes children being on one nap a day as they approach age three. That is a very wide window, and 11 months sits at the early edge of it.

What genuine readiness looks like

A toddler who fights the morning nap is probably ready for just an afternoon nap. But "fights it" has to mean most days over several weeks, not a rough Tuesday. Readiness shows up as:

• The morning nap refused, or pushed very late, on most days across several weeks
• Taking the morning nap reliably ruining the afternoon one
• Night sleep shrinking, or early waking creeping in, even after two decent naps
• Your baby staying reasonably cheerful through a missed nap instead of unraveling by late afternoon

The signs pointing the other way say the daytime sleep is still needed: sleepiness during the day, crankiness and moodiness that worsen as the afternoon goes on, hard morning wake-ups, poor attention, or a baby who seems wired rather than tired.

The look-alikes

Plenty of ordinary things make an eleven-month-old refuse naps for a week or two.

• Teething. The NHS lists "not sleeping very well" and being more fretful than usual among teething signs, and the first molars typically arrive around 12 months. Teething symptoms are often mild and last a few days.
• Separation anxiety. Beginning in the second half of the first year, it can cause many nights of disrupted sleep, with a baby waking repeatedly and crying anxiously for a parent. It usually fades somewhere around the second birthday.
• A cold or any short illness.
• Drifted timing. A morning nap that starts late pushes the afternoon nap toward bedtime, and late naps at this age interfere with night sleep.

Anything that changed in the last two weeks — a new tooth, a runny nose, a skill your baby is busy practicing, more clinginess in the daytime too — is a better first explanation than a permanent drop in how much sleep they need.

Things to try before you cut a nap

Napping helps a baby sleep better at night, so the first moves are adjustments, not removals.

• Move the morning nap later, in small steps, so it stops landing too soon after wake-up.
• Shorten it rather than cut it. Waking your baby from a brief morning nap protects the afternoon one, which is the nap that survives the transition.
• Keep naps away from bedtime. Set regular naptimes that are not too close to it.
• Bring bedtime earlier. When a nap is resisted or lost, an earlier bedtime is the standard fix — not a longer day.

Dropping to one nap while your baby still needs two produces an overtired baby whose sleep gets worse, which is easy to misread as proof the nap was the problem all along.

When the switch does come, it is messy

Expect weeks of both: some days needing two naps, some days managing on one. On one-nap days the surviving nap is the midday-to-afternoon one, and it often starts too early at first. An earlier bedtime bridges the gap on those days. What matters is the 24-hour total staying in range — 11 to 14 hours for a one- to two-year-old, including one or two naps.

If you log naps separately from night sleep, with a start and an end time, you can look at nap count and nap length across several weeks rather than reacting to three bad days. A steady decline in morning naps over a month is information. A rough patch during a cold is not.

When to talk to your child's doctor

• Loud snoring, gasping breaths, or any trouble breathing during sleep
• A temperature of 38°C (100.4°F) or higher — teething raises temperature only slightly, below 38°C, so a real fever needs another explanation
• Total sleep sitting well below the typical range week after week, or a baby who seems sleepy and hard to rouse during the day
• Sleep problems that seem severe to you
• Any question at all about your baby's sleep, including your own exhaustion — that is reason enough to ask
