She hardly naps anymore but when she does she sleeps about 1-2 hours depending on what time she falls asleep at, even though she doesnt nap she still has "nap time" where she stays in her room and plays or sleeps whichever she feels like, her younger brother still naps which is why she still has nap time too!
Hahahaha. It's been about a year since he stopped napping. I wish he still did. You could try moving his bedtime back a half hour or so (over time, it may help him get enough sleep to drop the nap).
My daughter naps for 45min-2 hours almost every day still but she usually is up early in the morning and has preschool half the day
