10 week sleep regression?!?

Jenni

Ugghhhh. My 10 week old had been going down for bed between 9 and 11pm consistently for two weeks, and staying down for 6-7 hours. Then last night she woke at 10:30 and would not go back down until 3am!!!! She did something similar but not as bad the night before. This sucks. I find this to be my least favorite thing about being a FTM...any words of encouragement or advice?
