2. In cases in which an interlocutory order was entered and both the report of visitation and final agency consent have been received, if (i) the child has been placed in the physical custody of the petitioner by a child-placing agency; (ii) the placing or supervising agency certifies to the circuit court that the child has been visited by a representative of such agency at least three times within a six-month period, provided that there are not less than 90 days between the first and last visit; and (iii) the court is of the opinion that entry of a final order of adoption would otherwise be proper. In cases in which the court entered either an interlocutory order or order of reference and the child was placed by a child-placing agency, the circuit court may, for good cause shown, omit the requirement that the three visits be made within a six-month period, provided that not less than three visits were made.
