Baby Sleep Schedule Calculator

Typical total sleep and general nap pattern by age — a starting point, not a personalized schedule.

Why there's no exact schedule here. Every baby's sleep rhythm is different, and no major pediatric body publishes down-to-the-minute nap times by age — sites that give you an exact clock schedule are not working from a clinical source. This tool gives the age-based ranges that real pediatric-sleep research actually supports (total sleep, general nap pattern) — not a precise plan for your baby.

Not medical advice. This tool gives a general estimate for informational purposes only — it does not replace professional judgment. If you're concerned, contact a pediatrician right away. This is general, population-level information, not an assessment of your baby's health or development. Every baby is different — for a schedule tailored to your baby, or if you have any concern about your baby's sleep, breathing, feeding, or development, talk to your pediatrician.

For ages under 1 year written in weeks, divide by ~4.3 — e.g. 26 weeks ≈ 6 months. This tool covers newborn through age 5.

Sources & how this is calculated

Total daily sleep guidance for babies 4 months and older comes from the American Academy of Sleep Medicine (AASM) consensus recommendations, formally endorsed by the American Academy of Pediatrics (AAP) — reproduced by Children's Hospital of Philadelphia's "Healthy Sleep Habits" and HealthyChildren.org (the AAP's own consumer site): infants 4–11 months, 12–16 hours; toddlers 1–2 years, 11–14 hours; preschoolers 3–5 years, 10–13 hours, all including naps. The AASM guidance doesn't cover newborns under 4 months, so the 14–17 hour newborn figure instead comes from the National Sleep Foundation's 2015 expert-consensus recommendations (Hirshkowitz et al., Sleep Health, 2015).

General nap-pattern guidance (how many naps, roughly when they consolidate or drop off) is from Mayo Clinic's "Baby naps: Daytime sleep tips": newborns sleep in roughly 3–4 hour stretches tied to feeding; after the newborn period most babies nap at least twice a day; many 10–12 month-olds drop the morning nap; many children still nap 1–2 hours in the afternoon up to about age 3; and most children have stopped napping by age 5.

What this deliberately does not do: give you an exact time to put your baby down, a precise "wake window" in minutes, or a fixed number of naps for your specific baby. Real babies vary enormously around these averages, and no major pediatric organization publishes that level of precision — tools that claim to are not working from a clinical source. If you want a schedule tailored to your baby, or you're worried your baby is sleeping much more or less than these ranges, that's a conversation for your pediatrician, not a calculator.
