Baby Sleep Schedule Calculator
Plan naps and bedtime from your baby's age and typical awake windows.
About the Baby Sleep Schedule Calculator
The American Academy of Sleep Medicine recommends 12–16 hours of sleep in 24 hours (including naps) for babies 4–12 months and 11–14 hours for 1–2-year-olds; the National Sleep Foundation suggests 14–17 hours for newborns. Awake windows lengthen with age. These schedules are a starting point; babies vary.
The formula
Nap time = wake time + awake window; repeat for each nap; bedtime after the last window
Worked example
Example: Suggested bedtime = 17:00
- Inputs: Baby's age: 7 months; Morning wake time (HH:MM): 07:00.
- Formula: Nap time = wake time + awake window; repeat for each nap; bedtime after the last window
- Result: Suggested bedtime = 17:00
