hi i am extremely concerned about my 7 yr old son. he has developed such a bad temper lately and screams and shouts at me and when i try to put him in time out or send him to his room he screams and shouts at me more. He has even gone a step further by kicking and punching me in the stomach and has even punched me in the mouth. He refuses to listen to any1 except from my father who is very strict but my son does not always listen to him either. He screams and cries like a 2year old if he can not get his own way and hates playing with toys, he only likes watching tv and playing computer games. He is also very needy for food and if he can not get food then he loses his temper and screams and cries again, the longest this has lasted for was 12hrs with only 6 hrs in between to sleep. Im at the end of my rope here and it is now becoming a huge problem within my marriage. What can i do??
