There is a Doctor Seusse book called "Would you rather be a bull frog or a butterfly". My parents bought it for me when I was a kid, and now my kids (particularly Meg) love it. The premise is that you are given a choice of being one of two things. You need to say which thing you would rather be.
My sister has turned this into quite a game with Meg. They take turns of asking "would you rather be…" and then answering.
A few months ago, Meg posed the following: "Would you rather be a flying princess or a toiletries bag?". Talk about a hard choice! Whilst we all thought the obvious choice would have been flying princess, Meg would rather be a toiletry bag! Perhaps toiletry bags are exciting to 3 year olds.
