Asking for a friend and posting in aibu for better traffic.
Example. DC 16 lives with RP. RP and NRP share all weekends and school holidays 50/50 and with RP during the week at other times. Parents don't live local to each other. This is an ongoing arrangement between parents for many years. For NRP to be able to see DC, and for RP to have a break from being full time parent.
At what age would you expect that the rigid EOW and half of all half-terms to become flexible, and for the NRP to be able to arrange seeing the DC directly with DC? And why?
