Susan’s 7-year-old daughter, Kylie, has lots of friends. She plays soccer, swims, and sings in the choir. She likes to help her teachers and is the first one in class to raise her hand to volunteer. Even her parents’ divorce two years ago doesn’t seem to have had major repercussions: She merrily goes to her father’s house every other weekend and gets along well with her new step-siblings. To everyone who knows her, she’s the model of a well-adjusted child.
