DS is 9 and still at stage 3 which I know isn't great. I'm a single parent and can't swim, which obviously limits the amount of practice he can get in between lessons. I have repeatedly asked ex to take the DC swimming when he has them but he is a lazy areshole who prefers to let them sit on screens the whole time he has them as it's easier and cheaper.
DS had lessons booked in ex's contact time for a while, though I paid for it, as the pool is minutes from his house and he doesn't work, making it easier for him to take him after school, but he repeatedly 'forgot' so I take him again now.
This week they were doing the thing where they push off from the side then do a roll. Ds's attempts weren't great TBF but she was so harsh on him. He wasn't messing around but she told him he wasn't trying (I'm a sec school English teacher and have yet to master the art of knowing beyond doubt whether or not students are trying when not misbehaving) and told him he must practise more, helpfully suggesting he come after school and/or weekends. DS wasn't motivated by her tirade and I felt like an even shitter parent than I normally do. Only four kids were there and the other kids all did the manoeuvre. It was so awkward - parents were giving me sympathetic looks etc.
Aibu to complain? A 9 year old has no control over how often he is taken to practice and, given my circumstances I have limited control also. I don't pay good money for sale and I to be made to feel like shit...
