I don't think my son ever peed on me, but he got himself pretty good a few times! I'll never forget the day he peed right into his open mouth and eyes. He wasn't sure weather to cry or not because it scared him, but DH and I were laughing so hard.
He was maybe 3 months old at the time.
And then my DD, well the first thing she did when she came out was pee all over the doctor. Not what you usually expect coming from a girl.
