I Wonder

Why does it seem so amazing when your own children create things? Anything? Cards, pictures, cookies, stuffed animals ... babies ... ?
Today they were delicious chocolate cookies created from a cake mix. They were perfectly shaped and tasted like chocolate-flavored sugar cookies.
Yesterday there was a stuffed animal, a cat, made from a purple striped shirt, with two matching buttons for the eyes sewed on. It was clearly a creature, with each arm and leg, the head, the tail and the body sewed and stuffed separately and then joined together with thread. I took a picture of it.
I'm not sure why it's so amazing and incredible, since it is in our human nature that we all create.
