DS is almost 6 and he is very much a 12hr a night sleeper, but the problem is that he doesn't want to go to bed at night and actively keeps himself up so that he only ends up getting 8-10hrs. He is so hard to wake up in the morning and I feel so badly because I know he is tired. How much sleep does he really need still? Should I try waking him up earlier instead of letting him sleep in? Maybe that way he will go to bed earlier. Left to his own he will always sleep 12-13hrs at night.
