I actually got it too. There was a long time that my kids would not stir before 7 AM. I even got them to 8:20 at one point...it was heavenly.
There has been a change.
Now that Matthew can crawl, he thinks it's appropriate for him to wake up at 4:30, 5:00, 5:30, etc. It's not. I can say that in all seriousness...it's not. It's not appropriate and not appreciated. I am trying with all my might to convince myself that this is just a phase...that he'll fall back into the 7:00 wake-up time soon enough, but it's not happening. Instead of throwing myself off a bridge (like I feel like doing as I blindly stumble into their room searching for one of the 5 binkies that he has thrown out of his crib and shoving it into his mouth), I continue to try to put him back to sleep. I am steadfast in this quest and will emerge victorious! See? I'm trying to talk myself into it again! Gotta love delusional behavior in new Moms!!!
