Parents are expected to fairly modify the parenting plan as family necessities, illnesses, weather or commitments reasonably so require. The parents must work together in good faith to get any missed parenting time rescheduled to occur within a reasonable period of time, usually within 30 days. When possible, each parent must timely advise the other when scheduled parenting time with the children cannot be exercised.
