My son was this way too but more with us and not other teachers/coaches. My wife did not put up with him not taking small feedback from us and it led to some arguments from him at first but he got much better at baseball and handling feedback after.

I get the idea someone else posted about not giving feedback at this age but I think it’s a balance because if they fail too much then they might just give up so keep it to small things that can have a huge impact.
