No, my ex never asks permission from anyone to do anything. She has signed my daughter up for dance (a few different types), gymnastics, piano, karate, swim, t-ball/baseball, brownies, cheer, tennis, horseback riding, ski school and probably a few more I am forgetting. This isn't all at once, it changes every year or so and seasonally. My ex claims my daughter wants to do all of these activities, but when I talk to my daughter about it she seems only semi interested in anything but swim and the dance classes. I do think it is great that she is exposed to different activities, but it has really gotten out of hand. Her schedule is exhausting. Most of them last for a session or two, then she doesn't sign her up anymore because she has lost interest. She typically asks me to pay for half of the cost of the activities too. I told her I didn't have to pay for them since it wasn't specifically listed that I do in our court orders and I don't agree with her having so many scheduled activities, and she told our daughter that she couldn't take dance anymore because Daddy wouldn't pay for it. She isn't the most pleasant or fair woman to deal with.
I agreed to pay for dance, in full, if my daughter stuck with it (I don't like the pattern of starting and stopping every activity, I want her to learn that you work at things). My ex pays for all of the other activities that my daughter takes part in.
The weekend that I am going to the family wedding my daughter would miss a dance class, and probably a baseball game (the schedule isn't out yet). My ex has even gone so far as to threaten to not allow my daughter to come with me if I intend to "remove her from the state" for the weekend. It is a family wedding in New Jersey, we are leaving Friday when my daughter gets out of school (my normal pickup time) and coming back Sunday afternoon/evening. I bring my daughter to school Monday mornings on my weekends, so it will not interfer with school at all, just her weekend activities.
