Hello I'm a dad of 8yo boy. He is in year 3 . Since couple of years he stays with me 6 days per week because he chose to. I wanted to change details at school to be 1st contact but I was told that I can't. Because my ex applied for school when my son was very young it has to stay this way now. I explained to them that he lives with me but It got me nowhere. Today there was parents evening slots to book for next week. I waited on the app to book the very first slot. I did it. Then few minutes after I got email that because my ex is prior I need to book different slot. I think it's unfair, she only takes him once a week, I do all homework etc yet getting second class citizen treatment. Any advice?
