8 months: 2 naps
Most 8 month olds take 2 naps with wake windows of about 2:45, 3:10, 3:30 (hours:minutes), the last one before bed being the longest. A sample day with a 7:00 wake-up:
- 7:00 Wake up
- 9:45 Nap 1, 1 h 30 min
- 14:25 Nap 2, 1 h 15 min
- 19:10 Bedtime
Every baby is different. Use this as a starting point, watch for sleepy cues, and set your own windows in the app above once you know what works.

Questions
What is a wake window?
The time your baby is awake between sleeps, counted from when they wake up to when they fall asleep again. Windows get longer as babies grow: about 45 minutes for a newborn, 2 hours at 5 to 6 months, 3 hours at 9 months.
Are wake windows scientific?
They're rules of thumb from sleep consultants and parents, not a medical standard. Use them as a starting point and watch your baby: yawning, staring and rubbing eyes mean sooner, a happy baby who fights the nap means a little later.
Can I use my own wake windows?
Yes. Open the age chip, turn on your own windows and set each one, like 1:45, 2:00, 2:00, 2:15. Lull plans the day from yours instead of the age chart.
What happens when a nap runs long or short?
Tap Asleep when they fall asleep and Awake when they wake. Lull moves the rest of the day to match, and if bedtime would land too late it tells you to cap the last nap or skip it for an early bedtime.
