Ouch.

Well, we're experiencing some serious backsliding in the sleeping department. It started a couple days before Christmas and has been getting pretty crummy, to be perfectly honest. Acid-reflux has been suggested as a cause, but the Zantac ("baby z") we've given her hasn't really helped at all. It probably is something digestive, though. Last night we tried her sleeping in her car seat so she could be more upright, and she did sleep slightly better... waking at 11:00 PM for a feeding (but refusing to nurse, isn't that great?) and then at 3:30 AM for a diaper change, but then having to be awakened at 6:30 AM to go to day care. There seems to be very little rhyme or reason.
Joel thinks it may be that her room is simply too cold. We run a space heater in there and try to keep her well-wrapped, but again she did sleep better all bundled in her car seat. So right now we're at trial and error. Lots and lots of error.
