I tease you as I'm inflating the balloon. Are you sure you want me to keep going? Are you sure it can take more air before it bursts? If it pops, I'm going to blame you!
We then play a little game. I ask you if you want me to inflate 10 more breaths into the balloon, and we could them out. When it doesn't pop, I ask you if you think it can take 10 more breaths, and if you want me to try.
