You do not have to do anything more than what the parenting plan and other court orders specify.
Static court orders sometimes cannot meet the changing schedules of real life. If you think your ex husband is changing the schedules to be spiteful or for other unreasonable bases, you can stick to the schedule as provided by the court orders.
On the other hand, if he is changing the times because of unforeseen changes at his work and you think being with the father is good for the daughter, you can be flexible if you want. So that you can make your own plans, you would insist that the father follows procedures (such as coming within 30 minutes of a scheduled time, he pays for you to drive the daughter).
You two can take each other back to court to get new orders to fit the current situation. However, the process can be expensive and time-consuming, especially if there is no agreement and attorneys are involved.
You can review your specific facts with your attorney to see what legal options you have.
