The department or supervising agency may recommend to the court and the court may order that placement of the child in the parent's home be contingent on or delayed based on the need for such persons to engage in or complete services to ensure the safety of the child prior to placement. If services are recommended for the caregiver, and the caregiver fails to engage in or follow through with the recommended services, the department or supervising agency must promptly notify the court; and

(2) Notify the parent with whom the child is being placed that he or she has an ongoing duty to notify the department or supervising agency of all persons who reside in the home or who may act as a caregiver for the child both prior to the placement of the child in the home and subsequent to the placement of the child in the home as long as the court retains jurisdiction of the dependency proceeding or the department is providing or monitoring either remedial services to the parent or services to ensure the safety of the child to any caregivers.

The best interests of the child shall be the court's primary consideration in the review hearing.

The protocol revision and expansion shall be developed by the prosecuting attorney in collaboration with the agencies referenced in this act.
