My fellas (DH and DS) are, but my brother wasn't and he still to this day curses his dad for bullying mom into going along with that. Not sure why, don't really WANT to know why, but there it is.
Hope everything works out... the key, from what I've heard anyways, is hygiene. Get that straight and there's not a whole lot of other issues. But when you're talking about youngsters... yeah right... and add in that it's that particular area... and Mom's trying to explain when she's not packing the same equipment.
Best of luck with that one... one more reason to say Parenthood is NOT for the feint of heart!
