I love reading emails, posts, anything, about the funny things children say. So I have one of my own to add - just happened minutes ago.
Kate has the vacuum cord around her neck like a stethoscope and the conversation goes like this.
K: "I'm Doctor Kate, and you're my mom."
Me: "Hi Dr. Kate."
K: "Come over here and let me hear your bum."
Me: "My what?"
K: "Your bum."
Me: (slightly alarmed) ... "What do you mean?"
K: "You know ... what your heart says ... bum bum, bum bum, bum bum."
Me: relieved sigh/laugh.
