Your experience with sleep regressions

Okay all, just curious as to what your experiences were with your babies sleep regressions. I'm going through it now for like two weeks, my baby used to sleep great until he hit 13 weeks now he is up every other hour. I have tried laying him down awake and tired, it's a no go. He is a kinda fussy guy as is, so it really pisses him off and he won't calm down. I hear him wake up sometime at night and fall back asleep, so I know he is capable of doing so. From what I've read their brains are just doing a lot right now, but momma needs sleep =[ I look forward to reading your replies!
