How do you discipline an autistic child?

Just do the best you can all kids go through these phases. Every time he acts up punish him you don't have to give him whippings all the time only if he is completely out of hand. By punishing him take away things keep him from doing fun things talk with him and y'all practice on being a good child, manners and how to show respect . If he does good give him a little reward now and then just be patient it will work out. Good luck :).
