I'm reading my son a book today, about a turtle who has to go to the hospital for surgery on his shell.
Through the book, I'm using the storyline to try to explore the emotions that he's having at being so sick and in the hospital. We talked about being mad, and being sad. I took the opportunity to point out the helicopter that was on the hospital TV and said "I'd be scared to ride in a helicopter. Do you ever get scared?"
He answers, "Don't worry, mommy. I will take care of you so that you won't be scared."
