Head banging

Hi All,

I'm new to all this but felt this was my only way of getting help for my son and our family.

I have a 9 year old non verbal son. The most loving boy you could ever meet. In the last 6-12 months though theres been a massive change in his behaviour. His frustration has led to him banging his head not slightly but severely. To the point where he is losing his hair on the front. We have holes answer cracks in our walls from it also. We are at our wits end on what to do to help. Its causing a massive strain on our relationship.

He could head bang out of the blue and for no apparent reason. We really need help on this. We've been thinking CBD oil might be worth a try but was wondering what everyone else has to done to ease the issue.

Please any suggestions would be great
