I have been loving being a mom up until now, and for no reason at all, I have randomly become extremely depressed and can't stop crying. I am convinced that my baby doesn't like me. He smiles and coos at everyone else but me. He used to sleep on my chest and now he prefers to be in the swing as opposed to being with me. I feel like I am loing it. Can PPD happen this late int he game, or is it run of the mill depression?
