I also agree with stealth. It would be much easier if parents could just "get along". OP has stated that this seems to happen on all of his weekends. I happen to know a woman who does the same thing as ETG, she puts her children in a lot of activities and makes the dad feel bad if he doesn't let them go on his time (In her case though, gramma won visitation with the father and because gramma is involved the children, 12 and 16, have the right to refuse visitation if they don't want to go), so mom involves them in things and tells them that they have to tell their father and grandmother no. In the long run gramma and dad won visitation and she still gets to keep the kids at home because they get to do "fun things". My son is only 5 and so this is just starting for me. When he wanted to get involved in bowling, hockey and now baseball, I talked to his father first as it would interfer with some of his visitation, lucky for me dad didn't have a problem and has shown up with him or if he couldn't, allowed me to take him for the couple of hours. I divorced their father, they didn't and the X and I won't make them pay for it.
