About this tool

What does this tool do?

How much sleep children need in 24 hours changes with age. This tool uses the ranges in the 2016 consensus statement of the American Academy of Sleep Medicine (AASM), a statement the American Academy of Pediatrics (AAP) also supports. Enter the age and the wake-up time and it shows the recommended total sleep and the bedtime window that reaches it. Signed-in parents can log that day's sleep and see the average of the last seven days next to the recommended range.

How do I use it?

Start with the child's age; if you are signed in and the profile has a date of birth, the age fills in by itself. Then choose whether to calculate from the wake-up time or the bedtime, and enter that time. Under six years the recommendation includes naps, so you also need to select the total nap time, otherwise night sleep cannot be worked out. The result cards update as you type.

How should I read the result?

The duration is a range, not a single number: any value inside the range counts as normal. The bedtime is a range too; the earliest time corresponds to the longest sleep and the latest time to the shortest. Falling outside the range on one day is not a problem on its own, but if it happens regularly it is worth asking your pediatrician.

What this tool does not do

The consensus statement gives no range for infants under 4 months, because normal variation is very wide at that age, so the tool produces no number either. How many naps a child should take and how long wake windows should be are not part of the official consensus, and the tool does not invent them. Nap time is the value you enter; it is never estimated.
