Re: HELP! I can't survive like this!
I actually think his schedule is pretty reasonable (10 hours at night), though I know an extra hour in the morning would be nice! I think some two year old may sleep 12 hours at night, but mine doesn't. My son has always been an early riser, sometimes brutally so (before 5 am). For a good while now, his schedule has been similar to your son's and it works for him. (It also works for me because DH gets up with him.) He usually takes a good nap. I do not think there is anything we could do to make him sleep later.
Is it getting light out at 5:30-6:00 - maybe that is part of the issue?
