Today went better, but BT is still a struggle. I got her down following the BT routine at 8:10 without too much trouble. But she woke up within 10 minutes. Daddy went and bounced her back down, but again, she woke up after a few minutes. She's still up now (9:45pm). It's the same way she always wakes up these days: she rolls onto her tummy and instead of sleeping starts doing pushups and crying.
I don't know what happened. A couple weeks ago, I'd often find her sleeping on her tummy -- some of her best naps were that way. But now, she always wakes up at 45minutes turned onto her tummy, and later in the day she often wakes up soon after being put down, same thing. Note that she can only roll back-to-tummy, she still can't roll tummy-to-back. (Well, she's done it a few isolated times, but nothing regular.)
We've rearranged the BT routine based on what's been stimulating, i.e. changing into PJs turned out to be stimulating -- something about pulling stuff over her head, I think -- so we moved it up to the beginning:
1. Change into PJs and night diaper
2. Go for a walk around the neighborhood
3. Sit in the rocking chair and talk about our day quietly
4. Sit in the rocking chair and read Goodnight Moon (will cut this -- she seemed to perk up at the book)
5. Sit in the rocking chair and say good night to all the stuff in our room.
6. Turn down the lights and do bedtime feed (she seemed to perk up at the feed tonight, but I'm not sure about cutting it, because other nights she's gotten really mellow after it)
7. Turn on white noise, turn off lights, draw curtains
8. Put on sleep sack
9. Bounce + sing to sleep -- she falls asleep and then I put her down. I don't think we can do independent sleep for BT yet.
