Is he reading?

Quick one.

This morning while getting in the car, Kieran hopped up on the middle (where the brake is) to rummage around on the passenger seat where I keep his CDs. He grabbed a CD and handed it to me and said "I want the Ring around the Rosie CD." I reminded him that I picked the music in the morning and took the CD form his hand. It was my Really Rosie CD. Made me wonder if he's reading how else would have have made the connection of Really Rosie to Ring around the Rosie?

What do you think?
