-"You be the whale and I be Pinocchio." (oddly his favorite part of that movie)
-"You be the tiger and I be Baloo."
-"You be Mr. Fredrickson (or something close to that) and I will be Russell."
The above may make you think my son's life revolves around Disney movies, but just to prove that is not the case, here are a few more:
-"You be Aunt Emmy and I be Tinny." (...or Finny--I think he is starting to say it right, sadly)
-"You be Angela and I be Baby Cia."
-"You be Suzanne and I be Baby Margie."
-"I be Baby Kateri and you be... her momma." (sorry he couldn't remember your name Allie)
and my personal favorite:
-"You be Mary and I be Baby Jesus."-- proof that we teach him about some important things.
