Thank you so much for your help ,I Will Try the journal circonstances and see...

I agree with Lisapal that that is the aggression is very new your son may well be in pain or physically ill. Aggression is a form of communication, most often an expression of frustration in not being able to communicate what is bothering him. I would suugest having him checked over by a physical to rule out medical issues. Take time to reflect on possible changes in his environment. Sometimes it is the little changes that cause the most distress. Try to journal ecircumstances surrounding each aggressive outburst which may help you establish a behavioral pattern that may be emerging. Please let us know how son is doing and how you are coping.
