It's been 3 days in a row my little guy has either gotten up CRAZY early or in the middle of the night. You would think I have a newborn all over again.
I think, however, it's the whole transition to his "big boy bed." When he wakes up, I figure he looks around and still gets excited that he can get up and walk on out of his room all by himself ... instead of the rolling back over and going back to sleep.
I'm not sure how long it will take for that excitement to wear off ... if that's even what it is ... but I hope it's soon. This lady needs some Z's.
