About the Baby Nap Schedule Calculator

The Baby Nap Schedule Calculator helps parents create a realistic, age-appropriate daily sleep plan based on their baby’s age and wake time. By balancing wake windows (the time a baby can comfortably stay awake) with nap opportunities, this tool reduces overtiredness and supports better nighttime sleep.

Why Wake Windows Matter

Wake windows grow longer as babies age. Putting your child down too early may cause short naps, while keeping them up too long can lead to overtiredness, fussiness, and more night wakings. This calculator adjusts wake times for each stage of development, helping you find the sweet spot.

Wake Windows by Age (Quick Guide)

Age	Wake window	Naps
0–2 mo	45–90 min	4–6
3–4 mo	1 h 15 min – 2 h	3–4
5–6 mo	2 h – 2 h 30 min	3
7–9 mo	2 h 15 min – 3 h 30 min	2–3
10–14 mo	3 h – 4 h 30 min	2
15–23 mo	4–6 h	1–2
24–36 mo	6–8 h	0–1

How the Calculator Works

Adjust the schedule based on your baby’s sleep cues (yawning, rubbing eyes, crankiness).

Tips for Better Nap Schedules

If bedtime drifts too late, shorten the last wake window or cap the last nap.
On no-nap days, plan an earlier bedtime to avoid overtiredness.
Babies thrive on routine, but flexibility matters — some days won’t go perfectly.

Note: These are general sleep guidelines. Always adapt for your child, and consult your pediatrician for medical concerns.
