Soren's Bum Woes

The other day, after returning home from a doctors appointment, Soren and I were hanging out in the living room. I was reading a book while he poured over youtube videos of Agry Birds. Suddenly he turns to me.
"Mom, my bum hurts."
"Your bum hurts, huh? What kind of hurt?"
He starts to scratch his arse. "It's itchy."
"Ahh," I say as  I hop off the couch and head over to him. "I think we can fix that. Let's go wipe your bum and see if that helps."
"No Mom," he says "that won't help. I think I need to go to a bum doctor."
