Holy crap...this kid was up almost hourly starting at midnight and then she'd stay and hang a bit too...wtf? She does have a cold and she is teething but she usually STTN pretty well! I don't think she got up this much when she was born.
My LO started thus at 3.5 months. It is horrible after being used to STTN. Some babies have it for a week and some for a year. I'm hoping she gets through it soon. It's seems like a growth spurt and teething at once.
