Ha ha! I'd take it as a compliment! Wish someone would say that to me :) I agree-- I don't think it's anything to worry about.
Nothing to worry about. Everyone is completely different and depends how you you carry the baby too.
Everyone is different...there is no "normal" but everyone said the same thing to me when i was late pregnancy with my first...im almost 19w now and have only gained 4lbs this time...i wouldnt worry if your drs arent :)
