re: Colicky baby - I'll never sleep again

I was going to say let her sleep in a swing, that way she is at an incline. Both of my kids slept in swings until they were around two months old. Also, if she's on formula, try switching to something different. Or if your wife breastfeeds, maybe try to avoid gassy or spicy foods (not sure how true this is, but doesn't hurt to try!).
Also, hire a baby sitter or have a family member come over and take care of her for awhile so you can have a break!!!!
