What do people call the groin area when talking to their toddlers? We want a unisex term as my 21 month old son calls both front and back in men and women, "bum". We call his genitals "willy and balls" but this obviously isn't going to cut the mustard when talking about mummy! I have tried calling it "groin" but this seems terribly formal, and a bit hard to say, as is "front bottom"! I am not too worried about this issue but just interested to hear how other families sort out this delicate naming dilemma.
