This is one thing I'm not quite sure what to do when it comes to Evan. I want him to know those words and body parts are normal. I don't want him to feel shame or embarrassment. BUT, when he's older, I also don't want him pointing at people's crotches and telling them they have a penis/vagina, or whatever else kids do!
For the parents of older kids out there: how did you handle this?
For everyone: why do you think these words are so "taboo" in our culture (or at least in North America - is it different elsewhere?).
