behaviour

[stelly1]

My 5yr old son has become extremely emotional, angry and some time aggressive since start yr 1 at school. He is fine when visiting with other people (friends and family) but as soon as i turn up his behavior changes dramatically. I am struggling to cope with how he has changed and his anger towards me. He cries at everything, he is in tears at least 5 times a day, he shouts at me and on occasion lashes out too. He is an extremely affectionate boy usually, and I praise him for good behavior and tell him I love him several times a day. I need help with what to do to help him through this as he then gets upset about his outbursts saying ' i cannot help it mummy, i am turning into a naughty boy and I don't know why' and ' i cannot stop it mummy' this is breaking my heart! HELP PLEASE
