My 4 year old usually asks her best questions while on the road. Coming home from swimming lessons we had this conversation:
Her: Mama, what will happen if I bite my finger off?
Me: Well, you'll be short one finger.
Her: But my fingernails grow back.
Me: There are some parts of our bodies that grow back when they get cut off like our fingernails and our hair. But most of our body parts dont't grow back.
Her: silence . . .
Me: thinking . . . Did I have thoughts like this when I was 4?
