(a) If the court awards parenting time to both parents under Section 602.7 or 602.8, the court may consider, consistent with the best interests of the child as defined in Section 602.7, whether to award to one or both of the parties the right of first refusal to provide child care for the minor child or children during the other parent’s normal parenting time, unless the need for child care is attributable to an emergency.
     (b) As used in this Section, “right of first refusal” means that if a party intends to leave the minor child or children with a substitute child-care provider for a significant period of time, that party must first offer the other party an opportunity to personally care for the minor child or children. The parties may agree to a right of first refusal that is consistent with the best interests of the minor child or children. If there is no agreement and the court determines that a right of first refusal is in the best interests of the minor child or children, the court shall consider and make provisions in its order for:
