Thanks Shiv and V!
V - that's similar to what I was planning on doing before the early NW started. I thought I'd move it up by about 15 minutes every 3 nights or so, but now she keeps beating me to it. We started at 10:30, and I was going to move it to 10:00 the last 2 nights, but she's been up before that both nights. She's sleeping really restlessly, too - I can hear her moaning and moving around through the monitor for most of the evening. I have a video monitor, and she's not awake, just flips her head back and forth and repositions lots. I don't believe she does this after the DF, just before. Of course, I'm asleep after, so I'm not as attuned to what she's doing.
Shiv - I wondered if it's developmental, too. She's been standing for about 2 months, but just figured out how to stand in her crib in her sleep sack about 3 weeks ago - a week or so before this all started. She's also babbling a lot more, so maybe she's on the verge of telling me something?
She dropped her catnap about 4 months ago, and only gets 3 hrs of daytime sleep at the most. Some of her naps have been crap during the last couple of weeks, too - we've had several 40 minute naps (she usually takes 2 x 1 1/2 hrs). She doesn't seem to be in any pain, and she really doesn't seem OT either, although I know she must be on the short nap days.
As for when she wakes, it depends on the time. If it's before DF, she just pops right up and stands there jumping up and down and screaming. I've been settling her back if it's before 9:30, and it usually doesn't take long. I just pick her up if she's really hysterical, sway with her for a minute, and then put her back and she's usually out within 15 minutes or so. If it's after 9:30, I go ahead with the Df. If it's after DF, she does the same popping up and screaming thing until I come for her, and then she just lies there, wide awake, staring at her crib bumper and not sleeping. If I sit down or leave the room, she jumps back up and starts with the screaming again. Last night I did shh/pat from 2:15 until 3:15, gave her some water at 3:15, and then she started screaming and crying and I couldn't calm her, so I fed her at 4:00. It was still another 25 minutes after that before she fell asleep. I don't really think she was hungry, just needed help calming down. She doesn't feel hot or cold, and it's not really her pain cry, just her frustrated 'why can't I sleep?' cry. This is similar to what she did around 5 1/2 months, just before she started crawling, sitting up, pulling up, and popped 2 teeth (that all happened within the same 2 weeks). Maybe she's about to walk, talk, and have 2 more teeth?
