The natural rights of parents presume the obligation to protect children and not harm them. State intervention is appropriate as a last resort when parents pose a risk to their children’s health or safety. Nevertheless, the proper balance of power between citizens and the state requires a narrow definition of harm.
Coercive state intervention in the family should be limited to cases where (1) serious physical or emotional harm to the child is imminent and (2) the intervention is likely to be less detrimental than the status quo.
