What do I do?

For a couple of months Noah was waking up at 5am. Ready to face the day. I was not so ready. It did not matter what time I kept him up until, he would wake at 5 on the nose. On his birthday he stayed up until 9pm and slept until 7am. It was glorious! So this last week we worked on a new schedule and he would stay awake until 830 and sleep until 730. This morning I woke up at 7 and went about my day. The time is now 824 and The Bear still is not awake. What do I do? Obviously he is tired, but can you get to much sleep?
And another question to all you mothers. I started giving Noah whole milk last night, and he hates it. What do I do there? He is supposed to have it right? He is still breast feeding, but I am pretty sure I read that he was supposed to have whole milk at age 1. I am going to ask the Dr tomorrow at our well baby check, but mothers advice is so much better coming from a woman!
