DH here for first posting so hope I get all the terminology right. DW has been going through PND - DS born 15 months ago - and is exhibiting all sorts of compulsive behavious.
First concern is she has put on a lot of weight. I know that is common but she never eats much when I am home. Based on the way food appears and disappears I suspect she goes through periods of eating lots then fasting. Other oddities include compulsive shopping for baby's clothes. OK this is from a charity shop but the house and loft are now full of bags of the stuff. DS never wears the same outfit twice! Last year it was garden plants. Bags and bags bought, planted and later dug up. When I confront her (try to be sensitive) she bursts into tears and runs away saying she doesn't want to discuss it. Ideas?
