It seems to be mostly teething since she doesn't eat more than 2 ounces each time she's been waking up. Once she doses back off to sleep, she stops eating and is ready for her bed. This week, she hasn't been fussing much when she is put in her bed, but on occasion she still kicks her legs. I guess she has too much to do, even in her sleep.
The top teeth seem like they are close to breaking through. Once they do, I hope her sleeping improves and her eating returns to normal. Right now, she is just chomping on the spoon because it feels good. The food is secondary. When she isn't teething, she eats like a horse and sleeps, well, better than she does now. Let's hope that routine returns soon.
