I don’t know what to do ....

Ch

My son is 14 months and if he doesn’t get his way he screams and cries and hurts himself any way possible . If it throwing himself off the couch smacking himself or just hitting his head on the wall or floor . He also will gag himself . We tried the whole ignoring thing but he gets louder and just does it more . I’m lost on what to do . I can’t get him into doctors cause of work . It makes it hard to find babysitters cause nobody wants to keep him with the way he’s acting .
