Its hard to encompass and huge amount of detail here, but my SIL suffered with PND when she had her second dd whom is now 8. All was well with her first dd who is now 10. My SIL has always been anxious, she is a sahm and never goes out in the evening and doesnt drive so she is home all day by herself, although sometimes she helps out at school. her dh works a lot, does 12 hour shifts. Her "estranged" father was found ill at christmas and is now living with social services whilst awaiting his op next month, this renewed contact with her father has been stressful for her, during this time dd2's behaviour has once again got bade, abusive to teacher hitting out at other children, generally very difficult, wont listen, says nasty things. My SIL today told me that she doesnt hug dd2 or say she loves her and her doctor thinks this all stems back to her PND. As a family its always been clear to us that DD1 is the favourite. I think DD2 feels all this anxiety and favouritsm and her behaviour is a result of it. I am no expert on this and wondered if what I have said here rings a bell with anyone and if there was any organisation which might be able to help her with her feelings towards her DD. As a person you never know where you are with SIL, one day she will say she is doing something and the next when you ask how it went it didnt happen. Its been like this for years. I want to help but dont know how.
