I don't want to jinx anything, but after a week I think it is safe to say that we are finally there! We are officially on the 2-3-4 schedule! Woo hoo!
Logan has been starting to wake up consistently around 7 AM. He goes down for nap(in his bed!) about two hours after waking up. He actually naps for at least an hour and a half, as opposed to his previous 30 to 45 minutes.
Once he gets up, he is up for about three hours. Then he goes back down (in his bed!) for his afternoon nap. He once again sleep for at least an hour and a half. Once he wakes up, he is up for roughly four hours before it is time for his 7 o'clock bedtime.
He has also gotten use to sleeping on his stomach, so once he rolls over he can put himself to sleep. He still wakes up in the middle of the night upset about it sometimes, but it is not nearly as bad as it was when he first started rolling over.
The next step is to get him to stop waking up for that middle of the night feeding, and then we are golden. Olivia gave it up on her own around 7 1/2 months. He seems to be doing a few things earlier than her, so I'm hoping this is one of them. Maybe in a few weeks when he starts solids?
