ANY conditions that you want. if you two can't agree, it will go to court which your lawyer can be there for Are they not allowed at mediation or are they just busy?
Exact schedule, any restrictions you want to put on him, basically ANYTHING you want can be brought up. I didn't want my son going over BDs dads house so that was included.
Also if you don't want your son to be introduced to all his new girlfriends you can say they have to be dating for at least 6 months or a year or whatever you want before they get intrpduced, talk about who's allowed to babysit, say that like he can't have anyone babysit unless he's asked you first and you can't do it, and nobody that you don't know.
my friend whos ex is deployed gets thier son i think she said it was 7 weeks in the summer and if he cant have him his family is allowed to have time with him (its because they live in different states) then he technically gets in a week during xmas break and he can have ever other weekend if he is in town
