How This Calculator Works

This calculator is designed around the key nap transition period for toddlers:

12-14 Months: Most toddlers are still on 2 naps, with wake windows of 3-4 hours.
14-18 Months: This is the prime transition time. Wake windows are lengthening to 4-5 hours as they move to one nap.
18-24 Months: Your toddler is likely on one solid nap, with wake windows of 5-6 hours.

Using the right wake window prevents overtiredness and helps make the transition to one nap much smoother.
