Maybe its just me and I'm wierd but doesn't bother me - though has mainly only been friends who have done so as we don't have family in Australia. My hairdresser did have a rub without asking (while not a friend have been going to her for years) but haven't had complete strangers coming up to me.

I think of it as them being excited for me - like Murph01 - ours is an IVF baby so we have waited for a long time for this moment so am making the most of it .................... will probably be a lot better than the "jelly belly" I'll be left with after the big day - Im sure I won't want people rubbing / jiggling that
