I've seen this on blogs & Kelly has done it a few times with Eileen. I've tried asking Cooper questions before, but he hasn't really gotten the idea and most of the answers end up being something he's playing with or eating at the time.
Yesterday we walked to the park to get out of the house & I quizzed him on the way.
What is your favorite book?
-Going on a bear hunt (he just read that book earlier in the afternoon)
What is your favorite movie?
-Mater (and he'd just watched Mater's Tall Tales before our walk)
What is your favorite song?
-Jesus loves me the little children (this would be a combination of Jesus Loves Me & Jesus Loves the Little Children. He prefers to combine them on a regular basis which makes a sing-along impossible)
What is your favorite color?
-Red like Spiderman & Lightening McQueen & Mater
What makes you happy?
-Milk
What makes mommy happy?
-Coffee
What makes daddy happy?
-Coffee too!
What makes you sad?
-Like when I cry? (this really confused him)
What are you going to be when you grow up?
-A swimming pool (we happened to pass the pool when I asked this and I couldn't get a different answer out of him)
What is your favorite thing to eat?
-Pizza and oranges
