My almost 36 month old's tantrums are increasing in intensity and frequency. He screams, bangs his head, throws things against the wall etc. He now has about 7-10 a day whenever he is corrected or thwarted in anyway. Our response has been to put him in his room until he is calm, usually about 10 minutes. Otherwise he is happy,engaging, does great at pre-school and in public. Should we just stay the course?
