How awful for both of you!! Have you made an appointment with the teacher to talk about your concerns? Or if theres another child he’s particularly friendly with who they could perhaps arrange a buddy system with to help get him more involved or strengthen his confidence?
I know from my sons school that I was also getting annoyed about the star of the week situation! I would certainly see what the teachers thoughts are about what’s happening in class and the crying incident! If you’re not happy take it to the head! Good luck xx
