Operation "Sleep In Your Comfortable Bloody Bassinet, Damnit" is in place, and seems to be seeing some success. Put Jack down for a nap at 2, he woke up immediately, got him back down, woke up again, back down again, and now asleep for over an hour and a half. I'm sure it's really hard to get used to sleeping there, so I'm making him nap there during the day so that nights stand a chance at improvement.
The last three nights I've gotten an initial 3 hour stretch when he goes down for the "night", and I haven't yet been smart enough to go to bed at that same time. Then he's up and down all night. He wakes up, nurses, falls asleep, all very promising. But when I put him back in the bassinet, he wakes up repeatedly. Poor baby, and poor mama too.
But he's awake during the day a lot now, and I see progress. We're getting there.
Jack, ready for a walk in his Phil and Teds cocoon:
