My DC is in reception at school and already having issues with her coming home and getting upset over people 'being mean' to her at school. She said nobody ever wants to play with her and some of the boys have been pushing her 
I was bullied throughout my entire school life so I want to do what I can to encourage her to be a confident child. We've done the whole tell the teacher, etc but I know kids can be cruel and that doesn't necessarily stop them from doing anything - maybe just more careful in front of teachers.
Any tips for helping her build confidence and make more friends?
