My DS is only 10-months old but has started throwing huge tantrums. Putting him in his carseat/buggy makes him scream and go stiff so I can't strap him in, taking something away from him that he's not supposed to have results in him throwing himself backwards and screaming. He got my phone the other day and when I took it away from hime, he screeched at me and promptly bit my knee! Getting very embarassing as he's doing it in public. Any ideas on how to tell him off as at the moment if I say no, he just screams louder!!
