I had v bad PND after dc1 and 22 months later had dd followed by PND which was better than first but certainly not ideal. Spent a lot of time crying and the first few weeks with intrusive thoughts I really want to TTC for no.3 but hate the thought of a repeat. I think that I am generally much happier than i was. what, if anything (particularly during pregnancy) can i do to prevent PND. Would really appreciate your thoughts. Thank you.
