At the end of the day, the comment that was made about breastfeeding, was, as has been said, made by someone with servere PND. I know she certainly wouldn't have wanted anyone to leave the forum because of her and to be honest, she has posted saying that it's HER issue, not anyone else's, as have many of the PND ladies with BF'ing issues.
I really see no need to leave, but, if I'd posted this thread, I probably would now too because of the way it went. It's turned out to be really spiteful and horrible. Claire was saying goodbye, which was her prerogative and whilst I think she WAS doing the wrong thing in leaving, I think she deserved a decent cheerio from those who will miss her.
FWIW, I still don't think you should leave, Claire.
