Today's guest blog is from John, a former commercial airline pilot who has adopted four boys from domestic foster care as a single parent. John and his family live in southern California. 

This is not a promo to get everyone to go out and adopt a foster child. It is the journey I have been through with my four sons who came from foster care, we are adopted. Each one came home individually, and typically was about age 12 at the start of the adoption. There is a belief in child psychology that if you cannot make an impact with a child before age three, don't bother, everything is set in stone. Hogwash. Older kids can change, just like adults can change.
