X and the bathroom

X said his longest sentence ever this morning! "Daddy take a bath. Scrub, scrub!"

Also, whenever someone is in the bathroom, he starts to open the door, then steps back, points to it, shakes his head and says, "Busy."  But sometimes he can't help himself and he barges in anyway. None of the doors in our house have locks, and the bathroom door doesn't close that well. As a result, both kids regularly visit us in the potty. These days K usually doesn't come in unless he needs something, but X enjoys it as a group activity. He'll sit on the potty too. He used to try to get me to move over so he could sit next to me, but now he'll consent to sitting on the froggy potty by himself. Once he tricked me into taking off his diaper so he could sit on the potty, and then he took off running. Leaving the bathroom door wide open, of course.
