When a child experiences removal from parents and placement with foster givers, the resultant emotions may be anguish, terror and abandonment. These reactions will be intensified if actual abuse has occurred at home. The feelings are exacerbated when reunion is delayed. For these reasons, laws generally insist that such removal must be done cautiously and sparingly. Parents, children and families should be free of unwarranted government interference in child-rearing. With that in mind, the law customarily asserts that removal of a child is only justified by imminent danger to a child's life or health. Even in such an instance, a hearing and an order is required and a prompt post-removal hearing follow.
