AIBU To feel like a crap mum?

[CakeandCustard28]

My DS4 is a really lovely, intelligent boy but has his moments of hitting out like all 4 year olds.
He attends nursery, and has hit out a few times saying his friends have annoyed him. Teachers have been dealing with this putting him on time out, and I have been doing behaviour Reward charts at home with him to stop him hitting/pushing.
Teacher pulled me aside today and told me a few different parents have complained about DS, and not wanting their kids to play with him. (Although we’ve also had problems of said parents children hitting my DS leaving marks etc but I’ve never complained as I know they’re still learning at that age.)
I’m trying my best to stop this behaviour but this has made me feel awful like I’m not doing enough. AIBU to feel like this? Or are the other parents being unreasonable the kids who attend are 2-4 years old so surely it comes with the territory?

It is mean of them to tell you that other parents said that. And what exactly are you supposed to do about what other parents want?

My DS was a hitter. He turned out to have ASD. The school system is supposed to manage children with various forms of additional needs. If you are doing everything you can to address the issue, then there is not much point in feeling terrible.

Making it's not mean. Maybe it's to let the mother know how bad the situation is, now that other people want to avoid her son. Sometimes telling the parent actually makes them parent.
Not saying the op is a bad parent. But I fully agree with them telling the parent.
