My daughter is 5 months old, I read a lot about how well CIO has worked for some. Every time I think I'm going to try it I can't stand hearing her cry, it breaks my heart and I have to pick her up and snuggle her.  My question is to those who have tried it, how long did it take? How long did your baby cry? If it wasn't for my husband I'd co sleep forever but he is uncomfortable with it..
