Coparenting - which is 'his' day to pay nursery for?

[Unexpectedlysinglemum]

Hi all,
If you're coparenting and the other parent has a mid week overnight, do they need to pay for nursery or find childcare for the day that they sleepover or the next morning?

If child stays with dad every other Tuesday, does he pay for childcare on the Tuesday or the Wednesday?

My best guess is they are responsible for the day the child wakes up at their house and change-over is in the afternoon.

So they pay for the day they drop the child to nursery, and if the child wakes up feeling unwell they can be responsible for looking after that child at home on that day. It would be more complicated for them to have to communicate with you to make you take the day off and transport a sick child first thing.

That makes sense thank you!
