How the Child Sleep Needs Calculator works
These ranges follow widely used pediatric sleep guidance, counting naps: 12 to 16 hours for 4 to 12 months, 11 to 14 for ages 1 to 2, 10 to 13 for ages 3 to 5, 9 to 12 for ages 6 to 12, and 8 to 10 for teens. Enter age in years, so 6 months is 0.5. Needs vary by child, and sleep outside the range with daytime tiredness is worth raising with a pediatrician.
