What's this?

One of Jack's favorite books is First 100 Words. He loves to look through the book and play a game we call "What's this?".  How do you play....well, I point to a picture and ask him "what's this?", and he will say what it is.  Sometimes, he will point to a picture and ask me, "what's this?".  We play this game a lot and he knows almost every picture in the book. Here's a video of us playing our favorite little game.
