Overheard last night as Brother got dressed after his bath:
Brother: No, no [Little Bitty] - you can't touch that. That's my penis. You don't have a penis. You have a DIVINEJULA (said very slowly and carefully as if making sure she got the correct pronunciation).
We have made an effort to teach Brother the correct names for things, including body parts. However, I didn't correct him on this. 1) I think his word for it is rather nice. 2) I don't think I'm ready to hear him repeat the actual word for it.
