A page for each age, with the published total-sleep range for that age and a sample day you can build from your own baby's wake time.
Total sleep per 24 hours is published guidance. The American Academy of Sleep Medicine, in a consensus statement the American Academy of Pediatrics endorses, puts it at 12 to 16 hours for infants 4 to 12 months and 11 to 14 hours for children 1 to 2 years — both including naps.
Nap counts and wake windows are not. No medical body publishes them. They are conventions that circulate across pediatric sleep resources, and they are a useful starting point — but nearly every sleep-schedule page you will find states them as though they were established figures. On these pages they are labelled as convention, every time.
Below 4 months, the guidance stops entirely. The AASM issued no recommendation for babies under 4 months, judging the evidence insufficient. Our newborn, 2-month and 3-month pages say so and show the National Sleep Foundation's 14-to-17-hour figure instead, naming it as a different body using a different method.
The two bodies disagree. AASM says 12 to 16 hours for 4 to 12 months; the NSF says 12 to 15 for 4 to 11 months. We show the AASM figure from 4 months because the AAP endorses it, and tell you the other exists rather than picking one silently.
Wherever your baby sleeps, the AAP's safe-sleep rules apply: alone, on their back, on a firm flat surface that meets CPSC standards, with nothing loose in the space. Room-share for at least the first six months. A schedule never overrides that.
They are not a sleep-training method and take no position on any. They do not tell you when to drop a night feed. Sleep varies enormously between healthy babies, and a clock time built from a conventional wake window is not a standard your baby is failing to meet. General guidance, not medical advice — talk to your pediatrician about your own baby's sleep, especially about feeding or any change in breathing.
