Ours still sleeps a lot, but doesn't nap nearly as well as he did a week ago. He used to be able to sleep 2 hours at a time during the day (and I'd cut him off there most of the time). Now, he's constantly waking up after 20-30 minutes. Night time has been pretty good still though (2-3 hours at a time, and waking up to feed).
I thought DD was sleeping too much the past few days because she wasn't awake as much in the morning anymore, then I realized I have been reading some of her signals wrong. She's finally getting the sleep she wants since now I am letting her nap instead of trying to entertain her!
