I'm in the same camp as most of you calling it his penis. However, my husband has some real hang-ups
: and insists that we call it his "pee-pee" He thinks it is weird and doesn't sound right when a toddler or little boy calls his penis a PENIS. But HELLOOOO it is a penis. You would call your elbow, an elbow, so why not a penis by its proper name
. We have had countless arguments on this and he refuses to budge. So whatever, I call it a penis, and my husband calls it a pee-pee. My DS is 21 months and only says a few words, so he is not labeling it yet but when we ask him where his pee-pee is he points to his groin. When I ask him where his penis is he also points to his groin. So I guess he'll know it by two names.
