We've had a sleep revolution at my house. Petra has spontaneously started soothing herself to sleep in the past few days. We put her down and she sucks her thumb until she falls asleep, and when she wakes up she just lies there sucking her thumb some more. It's like a new toy for her and she seems happy to lie around testing it out for now. I'm sure she'll get bored with it soon, but it's very mellow here in the meantime.
And, Petra's going down for the night before midnight. A couple of weeks ago, I started rousting her out of bed at around 11:30 in the morning instead of letting her sleep on and on, in an effort to shift her routine. It seems to have done the trick. Petra's been in bed around 11pm for the past few nights. She's also started waking up earlier of her own accord – well before 11 this morning. The change in routine makes life much easier for me and Travis. We're a lot nicer to know when we're getting enough sleep every night.
