How to Use the Baby Sleep Duration Tool
Enter your baby's age and press Show Sleep. You get total sleep over a day, split into naps and night sleep.
Reading the result
Total sleep gradually falls from the newborn weeks to toddlerhood.
Daytime naps shrink and become fewer, while night sleep lengthens.
Some babies need more sleep and some less within the same range.
Look at a week of patterns rather than a single day.
