One DD. With one parent 4 nights and the other 3.
Everything is split evenly in terms of costs for clothes, uniforms, school trips, activities. Parents either buy what is needed themselves or if one pays a big cost, the other will send them half the money, one parent pays for one activity, the other parent pays for the second etc...
School drop offs and pick ups are done by whichever parent has them that day, same with appointments and other things.
Relatives provide minimal amount of wrap around care if required and as child is in school, no childcare is needed.
Mostly contact stays 4/3 but occasionally will stay with the other parent 4 nights instead of 3 and does sometimes have tea at the parents they are with 3 nights on the other parents night due to work.
