How do separated parents organise children’s activities with 50/50 custody?

[CaribbeanChaos]

When sharing custody of your children 50/50 (one week with each parent) how do you organise activities?

Do you discuss options with the other parent before suggesting it to the child as the other parent will need to take them to the activity on their time too.

or

Do you sign the child up and then inform the other parent once done that they need to take the child to the activity every Thursday or whatever?

or

Do you organise your own activities on your own weeks and the child does each activity bilaterally?

If it is something the child enjoys and both parents should try and let it happen

Cost wise very nice at the DAD pays for everything so the X should check with him before starting a new activity a.k.a. financial commitment

As a role, my friend shared the cost and try make it happen, but it does take some juggling, which is why they discussed it beforehand

Is your case the X hasn’t discussed it so going forward I would suggest any new activity that his weekly should be discussed before agreeing to do it
