I know a separated couple who have children and a set arrangement for days with each parent, that doesn’t vary unless there are exceptions made for special occasions/events or holidays. Both parents usually agree a variation with each other when taking the DC on holiday, or special occasions like parties, weddings etc, things that are outside of your control. Then contact just reverts back to the next set day.
Note: the holidays are the same length of time.
Parent A took the DC on holiday.
Parent B missed some set contact days due to the trip.
Parent B picked the DC up on their next allocated day after the holiday.
Parent B planned to take the DC on holiday.
Prior to the trip, Parent A asked for extra time with the DC to compensate for the upcoming holiday, in Parent B’s allocated time.
Parent B said no.
Parent B returned from holiday and DC went to parent A’s as per the usual agreement.
When Parent B’s set time came round again, Parent A again asked for extra time with the DC, on Parent B’s set days to compensate for the holiday days they had missed.
Parent B said no.
Parent A feels that they should be compensated for the time they missed with the DC that fell on their days.
Parent B feels the days should stay the same, not keep disrupting routines, each parent has had a holiday with their DC, and time with DC is not a repayable debt from each others time and wouldn’t expect this themselves.
