The 4 to 3 Nap Transition

Updated

Quick answer: Most babies drop from 4 naps to 3 between about 4 and 5 months. Signs include fighting the last nap, shorter naps, and a bedtime that keeps drifting later. To make the switch, stretch wake windows by 10–15 minutes and drop the late-afternoon catnap, with an earlier bedtime for a week or two.

How to make the switch

  1. Stretch each wake window by 10–15 minutes over a few days.
  2. Aim for the third nap to end by about 5 pm.
  3. Drop the fourth nap and move bedtime 15–30 minutes earlier for a week or two.
  4. Expect some mixed days. On rough days, a short fourth catnap is fine.

Common questions

How long does the 4 to 3 nap transition take?

Usually 1–2 weeks. Some babies switch in a few days.

Can I go back to 4 naps?

Yes. If your baby seems very overtired, add the catnap back for a few days and try again later.
