How much sleep does a 27-month-old need?

The AAP and CDC recommend 11–14 hours in 24 hours through age 2; the National Sleep Foundation range for ages 3–5 is 10–13. A 27-month-old usually needs 10–11 hours at night plus a short nap.

What wake window does a 27-month-old need?

About 6 hours before the nap and 5.5 hours after it. If either stretch runs long, look for the 5 PM slump — it means the post-nap window should shrink, not grow.

How long should a 27-month-old nap?

60–90 minutes is the sweet spot. Longer naps can push bedtime past 8:30; cap it with a fixed end time (same alarm, same quiet wakeup) if nights are getting late.

Is there a sleep regression coming for a 27-month-old?

You are inside the 2-year regression window (24–30 months). Night wakes and nap refusals come in waves; keep responses consistent and expect the waves to flatten toward 30 months.

27-Month-Old Sleep Schedule

Here is a realistic day for a 27-month-old: wake up around 7:15 AM, one nap at 1:00 PM, then bedtime around 7:45 PM. Wake windows run 5.5 to 6 hours, and total sleep lands near 11 to 13 hours. Shift any time 15 to 30 minutes to fit your family, consistency beats the exact minute.

What’s changing at 27 months

Night sleep consolidates while naps shorten. Watch total sleep: if bedtime drifts past 8:30 or mornings get earlier, shorten the nap rather than stretching the evening — the night is the foundation at this age.
