Kids generally start to stop taking regular naps between ages 3 and 5, with many children naturally dropping naps around 4 years old. By age 5, less than 30% still nap, and by 7, nearly all children have stopped napping. The exact time varies by child, and signs they are ready to stop include difficulty falling asleep at nap time, difficulty falling asleep at night, waking early, staying alert and happy without naps, and no longer sleeping during nap attempts. It's important to gradually reduce naps rather than stop abruptly, and occasional naps may still be needed after the main transition period.
