Baby Sleep Schedule Calculator
Typical total sleep and general nap pattern by age — a starting point, not a personalized schedule.
Showing an example
This tool covers ages 0–5 years (0–60 months).
For older children, school-age sleep guidance (9–12 hours/night) applies instead — see the sources below.
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.
Sources & how this is calculated
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.
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) and published as a chart on HealthyChildren.org, the AAP's own consumer site: infants 4 to 12 months, 12–16 hours; toddlers 1–2 years, 11–14 hours; preschoolers 3–5 years, 10–13 hours, all including naps — plus 9–12 hours for gradeschoolers 6–12 years, which is the figure shown if you enter an age past this tool's range. This tool's infant band stops at 11 months only because the published bands overlap at 1 year and its toddler band starts there. The published bands then jump straight from 1–2 years to 3–5 years with nothing in between, so a 2-year-old belongs to the toddler band and its 11–14 hours — that band runs to 35 months, which is why its label names its month range and not only its years. AASM's guidance doesn't cover newborns under 4 months, so the 14–17 hour newborn figure comes instead from the National Sleep Foundation's 2015 expert-consensus recommendations (Hirshkowitz et al., Sleep Health, 2015), reproduced in the table at Children's Hospital of Philadelphia's "Healthy Sleep Habits". One honest note: CHOP’s table follows the NSF figures throughout, so it lists 12–15 hours for 4–11 month olds where AASM lists 12–16. Where the two panels differ, this calculator shows the AASM/AAP figure.
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.
