I can't offer any behavioral suggestion,but I know there's almost a reversion in child's morality in different stage of life.for example,childs with sly behaviors in childhood usually become so courteous in adolescence or youth and vice versa.
however,life is a trade off between mental hardship and physical hardship,that every parent must manage it to have a normal child.

 

Or, as some say, "The apple doesn't fall very far from the tree". If her parents are "good people" the child has an excellent chance of straightening out by adulthood. I've witnessed it myself!
