Energy

I watch Natalie every day and wonder where she gets her energy. Literally from the moment she wakes up every day until the moment she crashes at night, she is running. Sitting still is a punishment for her. Even if she is "watching" TV she is running around, constantly moving and going. I don't get it. Why don't I have a third of her energy? Do you realize how much I'd get done in a day and how many calories I'd burn? It is probably a big contributing factor why she wears size 18 months shorts at 3.5 years old. Anything she eats, she burns! I want to bottle it and sell it! Great moneymaker!!!
