What's Protein For?

Kayla is definitely smarter than her age.

Yesterday, I gave her the option of chicken strips and carrots for lunch and she said, "Yeah, carrots!"

I told her no she has to have protein with the carrots and she replied, "Ok, chicken strips and carrots."

Later that night, about 5 hours later we were driving home from dinner and she blurts out of nowhere:

"What's protein for?"

Mike had no idea where that came from and I could only sit there and laugh.

Mike: "Its for building muscles."

Kayla: "Oh."
