Hi I just wondered if anyone else has or is experiencing similar problems. Our son is 3 years 3 months. About to start speech therapy but when he doesn't get his own way hits his head onto the floor or wall or hits it with his hand. In the past we have worried about autism but as he got older it doesn't seem to strike us or health visitors as that. But a possible development delay. After Dr Googles help I'm now concerned even more. If anyone has experienced similar please get in contact.
