Hi all, my 21 month old son knows the name of virtually all his body parts by now and everytime I bath him we go through all the parts of his body and say what they are called. He is now particulary interested in his penis and keeps pointing at it for me to tell him what it's called. The thing is do I call it by it's proper name or give it a nickname, my friend's little boy calls it his "little man"! I find it all quite amusing but should I be straight about it or keep it light hearted.
