My 7yo DS is becoming increasingly aggressive and blowing up from nothing. He is also increasingly hyperactive, initially at home but also now at school. Also using 'baby-ish' language and concentration has completely diminished. The behaviour looks like some aspects of ADHD, but he was fine before. As a family we have been through a major trauma and we could not shield him from all of it.
Please may I ask advice, as to whether this is normal in the circumstances and what the most appropriate help/management is (sorry, not writing from English)? Should we be really worried (we are) or is this a phase that should resolve?
