(b) The temporary order for visitation must provide that:
(1) the designated person under this section has the right to possession of the child for the periods and in the manner in which the conservator described by Subsection (a) would be entitled if not ordered to military deployment, military mobilization, or temporary military duty;
(2) the child’s other conservator and the designated person under this section are subject to the requirements of § 153.316, with the designated person considered for purposes of that section to be the possessory conservator;
(3) the designated person under this section has the rights and duties of a nonparent possessory conservator under § 153.376(a) during the period that the designated person has possession of the child; and
(4) the designated person under this section is subject to any provision in a court order restricting or prohibiting access to the child by any specified individual.

(c) The court may limit or expand the rights of a nonparent designated person named in a temporary order rendered under this section as appropriate to the best interest of the child.
