Hi, is there a rule that, at a certain age, children should not be sharing rooms? Is there a rule that sets out the sort of conditions required in regards to sleeping arrangements? Access and custody of children is 50/50. One child sleeps in what can only be described as a room that is supposed to be a bedroom (small single) but is now far more a store room for suitcases, boxes, etc. The other child shares with a stepsibling but when relatives visit, the child is given a mat to sleep on the floor in the living area, while the visitor and step siblings get the beds and room.
