For the past few nights LO wakes up anywhere between 4 and 5:30 a.m. and thinks it's party time. She gets up and starts to dance, bounce, sing, hit me in my face, crawl all over us, etc. We co-sleep, sometimes she's right next to me in bed or sidecarred in her crib. She'll stay up for 1-3 hours and then goes back to sleep. Right now her wonky schedule is okay since I'm not working but when I go back to work this will not work!

She usually wakes up around this time to nurse but she has always gone back to sleep.

I have no idea what to do. This is also messing up her sleep schedule at childcare. What the heck is up with her?
