My 1yo DS has discovered his screaming vocal chords. If he doesn't get his way (ie I take something off him he shouldn't have, he's hungry or thirsty, or I'm just not doing what he wants me to etc) he screams which varies from a deep gutteral dinosaur velocorapter(ah la Jurassic Park) like shriek/scream to a high pitched screetch.

Nothing I do seems to help. I've told him off, smacked him, given him a timeout, shrieked back. Nothing stops him from doing it. I have also tried ignoring him and that doen't seem to make much difference either. I'm at my wit's end! I get sympathetic looks from other mums and nasty dirty looks from childless professional women and men. It's driving me bonkers!! Please, can anyone help me?!!
