Exes Jeff and Valerie say they’re at a loss for how to help their 15-year-old daughter, Danielle, who they say has a history of lying, acting out and showing inappropriate sexual behavior. They say in kindergarten, Danielle began expressing herself sexually at school, and by second grade, was threatening physical harm and making sexually explicit comments to other students. They admit they have not been a united front while raising their daughter, who has been bounced around between them and her grandmothers while growing up.
