Last night I put E down at 9 (as usual). He sort of rolled around the crib chewing on his lovey for about 5 minutes, but didn't cry. And then he slept. And slept. There were a couple of times I watched him stir and sit up on the monitor but immediately fell back asleep. And slept. All night. Until 8AM. DH changed him and brought him in to me to nurse (and omg by then my boobs needed to be nursed on desperately) and then I put him back down in his crib for another two hours.
Night before last he only woke up once, around 7 hours after I put him down. This is such a drastic improvement from last week, when he was waking up every hour and a half or so. I'm hoping this continues!
