So don't. They love you unconditionally, so they don't really like it when you are angry. This is especially true when it comes to disciplining children with autism. Many times, they throw tantrums not physically hurting oneself or others, that is because they get away with them. Positive discipline works best in such a case. Reinforcing positive behavior is the key. And patience!Reinforce Good BehaviorReinforcing positive discipline works as well. Just as one goes about using disciplinary tactics with children, one has to also use reinforcements for their good behavior. When they learn a 'rule' effectively and learn to follow it, award them with praises and other small measures. This will encourage them to keep at it and over time it'll become a habit. Be Model ParentsChildren model their parents so make sure that you are portraying the same behavior which you are teaching them.
