just a little back story
Son & DIL have been together 8 yrs. She as an 8 yr old boy that only knows my son as daddy. Last yr shortly after a miscarriage she threw my son out because there was someone else, the thug is a drug addict and dealer(and physically abusive). When she threw out my son he moved back home with her son. This lasted 36 days.

Son and DIL had a baby boy 3 months ago. He was 8 wks premature and she was in the hospital on bed-rest 3 wks prior. Last week he was put out again. The boys, of course are living here. Including the infant, She see them a couple hrs a day max. The thug is back and she is trying to see if they can have a relationship.

Son is devastated and has been severely depressed since the last time she did this. To me she seems to play this "come here I need you, get away from me I don't want you" game. Son only wants her back and I am trying to get him to a dr for medication and therapy.

I just don't think it's natural for a new mother to just walk away from her infant. I think there is some kind of psychological problem, mainly postpartum. She comes from a really screwed up family where drugs and criminal activities are normal. Her mom and brother are dead, both passed before she set her hooks on my son.

So thoughts... postpartum or a bitch
