Pretty sure middly has elements of both. Camhs said pretty much the same but the dx of Asd is far more useful than one of fasd or fae. We know that bm drank - fc has told me she'd turn up for contact stinking of booze. Have no reason to think pregnancy would have caused her to stop. But I suspect that's true of a lot of our kids bps.
Mum to three easy to place babies! DS, Bigly (13), DS, Middly (10) and DD, Littly (8) with a range of diagnoses!
