We hasten to add that in determining whether a material change in circumstances exists for the purposes of s 128 of the WC, the court is required to balance several interests. This includes on the one hand, the need for stability in carrying out orders and establishing the post-divorce routine for the child over a reasonable period of time, and on the other, the need to be responsive to new developments. As to the former consideration, we recognise that it is not desirable for the parties and their children to be “in limbo”, where constant applications for variation result in uncertainty for the children and keeps the family in the “litigation box” even before there has been sufficient time for the new arrangements to be carried out or for routines to be set up. As to the latter consideration, we are cognisant that the parent-child relationship is dynamic, especially since children have new needs and preferences as they grow older. Thus, the court must also ensure that there is sufficient flexibility to adjust orders relating to the child’s arrangements to suit the current circumstances facing the child.
