Check recommended total nightly sleep against a child's age.
Sleep experts publish total-nightly targets that fall as children grow, from roughly fourteen to seventeen hours for newborns down to eight to ten for teens. The calculator picks the band for the child's age and measures tonight's actual hours against it. Consistently missing the sleep target shows up in mood, focus and health, so a simple comparison helps families spot a real problem early.
