I've never been able to get nap time down since Avian was born. Even if I get him up by 7 or 8 am he doesnt want to nap until like 2 pm and no matter what he always wants like a 2 hour nap. So either he sleeps till 4 and doesn't go to bed until 10 pm or if I cut his nap short he's either a grumpy gremlin for hours or cutting his nap short doesn't make a difference and he's up until 10 pm anyways. Aren't kids this age supposed to need more sleep? At this rate he's going to be up until midnight when he's 4 years old.
