How much sleep does a 13-month-old need?

The AAP and CDC recommend 11–14 hours in 24 hours for babies aged 1–2 years, and the National Sleep Foundation agrees for this age. At 13 months that usually means 10–12 hours at night plus about 2.5 hours of naps across the day.

What wake window does a 13-month-old need?

About 3 hours before each nap and 3.5–4 hours before bedtime. If your 13-month-old rubs their eyes before the window ends, put them down early — an overtired toddler fights sleep harder.

Should I drop to one nap at 13 months?

Not by the calendar. Most children move to one nap between 13 and 15 months. If the second nap is refused three days a week for two weeks, push the first nap later by 15 minutes every few days until it becomes the single nap.

Is there a sleep regression coming for a 13-month-old?

The 12-month regression window can stretch to 15 months for some toddlers: sudden wakes, short naps and clinginess. It usually passes in 2–6 weeks — keep the schedule steady and expect gradual improvement.

13-Month-Old Sleep Schedule

Here is a realistic day for a 13-month-old: wake up around 7:00 AM, two naps at 9:45 AM and 2:15 PM, then bedtime around 7:00 PM. Wake windows run 3 to 3.75 hours, and total sleep lands near 11 to 14 hours. Shift any time 15 to 30 minutes to fit your family, consistency beats the exact minute.

The 2-to-1 nap transition is usually starting: the second nap gets shorter, slips later, or vanishes some days. Morning wake windows stretch past three hours, and bedtime can jump earlier for a few nights while everything resettles.
