i need some voices of wisdom please! my eldest son is nearly 10. up until this last year he has been a wonderful son,one to be really proud of. but something's changed..he's getting into trouble at school nearly every day. he fights other boys in school and comes home really upset.he's bullying his younger brother(who's 7) and has him in tears every day.he's constantly flying into a rage at the slightest thing, and he's become cheeky and lippy, especially to me and his nan. im not really sure how to handle it.we don't smack our children but last week he tried to fight with me and started punching and kicking me..any tips on how to best handle this situation would be appreciated.
