You know what my pet hate is during pregnancy? People who say "Now I can call you fatty". Beg your pardon?? You decide that the most sensitive phase of a woman's life is the best time to make value judgments on her physicality? You idiot! Whether you actually put weight on or not doesn't matter (cos I've heard - oh, but you're so small, it's just a joke...so, if it doesn't actually apply, don't say it, moron!), IMO.
That and stating whether you are carrying small or big or high or low or 'definitely' a boy or girl are all dumb things to say and people need to reinsert brains and filters!
