Custody agreement

My soon to be ex and I are sitting down tomorrow to work out custody. We are trying to do this without a paying a mediator by the hour. We are going to run our final agreement through an attorney though. She advised us to try to write up an agreement together and she would turn it into a legal agreement once we have our written out agreement.

What are some little custody points that aren’t obvious that you have in yours that you think we should include?

I’m thinking beyond the obvious things like schedule, child support, holidays.
