Dh and I can only agree on Sophie at the moment (early days - long time to go) but though I think it is a lovely name I had a lisp as a child (resolved with speech therapy and just getting older) and if my name has an S in it I'd have been so embarrassed to ever say it. Is it likely to be inherited - should we avoid Ss? At very least have an obvious non S nickname (can't think of one for Sophie).
