Notices which are withdrawn or varied as a result of the child being born or placed earlier or later than expected, will be disregarded.
Bydd rhybuddion a dynnir yn ôl neu sy’n cael eu hamrywio oherwydd bod y plentyn wedi cael ei eni neu ei leoli’n gynt neu’n hwyrach na’r disgwyl, yn cael eu diystyru.
