There is Something Special about a Daddy and his Daughter

Last night I caught Phillip and Trystan on video laughing at each other. It was the most awesome thing to watch!
Why is it that a Daddy can make his daughter smile like no other person can?
Why is it that a Mom has such a closeness to her son?
All these things amaze me..and yet I know that God knew EXACTLY what he was doing when he created children. He knew that they would bring the MOST happiness into a Husband and Wifes life!

I've included the video clip of Phillip and Trystan. Make sure you watch the whole thing because Trystan doesn't start laughing outloud until the end!
