Why Baby Sleep Changes So Quickly
In the first year, sleep patterns shift fast. Newborns sleep in short bursts, but by 3–4 months your baby begins to follow more predictable wake windows. By 6–9 months, naps lengthen and many babies follow a 3-nap schedule. Near 10–12 months, most babies settle into a 2-nap rhythm with longer awake stretches.
This calculator adjusts automatically to reflect normal developmental patterns — helping you stay confident and consistent during each phase.
Baby Sleep Schedule Examples by Age
Here are common nap patterns this calculator may generate:
- 0–3 months: 4–6 naps, short wake windows (30–90 minutes)
- 3–6 months: 3–4 naps, gradually lengthening wake windows
- 6–9 months: 3 naps, longer morning nap patterns begin
- 9–12 months: 2 naps, 1–2 hours each
Every baby is different — but these age buckets help you know what’s normal and what to expect in the months ahead.
