H: How long does she have to wear the cast on her leg?

Me: I think for about 6 weeks.

H: WOW, that's a long time.

Me: Yes, it's almost 2 months, it takes the body a while to heal.

H: Why does she have to wear the cast to heal?

Me: The cast holds her leg still and keeps the bone in the right place and then new bone grows and fixes the broken bone.

H: How does new bone grow?

Me: Your body uses the vitamins, minerals, and nutrients inside of it to create new bone. Isn't your body incredible?! And your brain helps tell your body where to make the new bone! Our bodies are amazing aren't they?!?!

H: And also...(slight pause for thinking)...my penis is amazing.

What can I say, he's a mini-man.
