I think if the only obligation for you is to make her available for contact, you communicate with the centre that dd will be made available on these dates as per the order and that he needs to confirm that he will attend up to the day before. No confirmation, no visit.
Then follow through and keep using the same terminology “dd is available for contact on x date, kindly confirm your attendance by close of day before so that we know the contact is going to take place. If no confirmation is received, we’ll repeat the same process again with the next scheduled appointment.
Make up sessions may be accommodated whenever convenient, but again subject to confirmation to the contact centre.
What he thrives on is hurting you, controlling you. So if you don’t initiate the communication, if you stick rigorously to the every other week, he’s going to have to fit in or he won’t have access to you or to her.
Leave the ball on his side. You don’t need to deviate a millimetre from the court schedule. He’s either available or he’s not.
He won’t like having to answer to you, so I guess he’ll not bother
If you relentlessly keep to the script so there is documentation that you’re making dd available and all he has to do is (a) confirm and (b) turn up, and he doesn’t bother, it’s not you breaking anything.
