Sibling Rivalry Already?

Xylie and Zayden adore each other. Lately, however, they have had a few spats over a toy...Race Car Lightening McQueen to be exact from the movie Cars. Zayden has never seen the movie but that Y chromosome he has gives him the uncanny ability to recognize a quality race car when he sees one. Whenever Xylie plays with the now faded and scratched little car that she acquired from a Happy Meal, Zayden crawls at race car speed to swipe the car. And, to his defense, it has been swiped from him as well. Xylie usually relents since he is a baby, so they don't get brutal with one another, but Zayden has claimed that car as his and "drives" it around the living room saying "broooooom......brooooooooom."
