"Privacy please"

We've been trying to teach Morgan the concept of privacy. We've had problems with her intruding on Daddy's bath time or potty time. To avoid a way too complicated discussion with my two year old, I introduced "privacy." I'd say, "Daddy needs privacy" when she tried to follow me in the bathroom. I think she's starting to understand the concept. Now, when she goes to the bathroom, she says "Morgan privacy please, shut-door." Just a word of wisdom, don't leave a two year old in the bathroom by herself for too long. Privacy is not the same as playtime.
