Moms, I need some help?

4 months old is way to young to even consider the CIO method. I do not agree with it in anyway. Even those who use it say to wait till at least your baby is 6 months old. We have a routine for my son before he goes to bed. He gets a bath, then a bottle and then my husband sits with him on the recliner till he starts to drift to sleep and then moves him into his crib. Sometimes he just puts him down and he goes to sleep.
