answer:I hope you mean discipline = teach and not punishment. With an autistic child, you must exercise a tremendous amount of patience, and supervision. Each child is a unique situation, but for the most part, restraining from the activity you wish to avoid is the best way. This is usually by taking him to a different location. Other, more drastic means are holding them until they behave, even while they may be kicking and screaming, or putting them in a restrictive area, such as using a fence in one corner of the room. I suggest you join in some of the support sites that you can find on the net. You can eliminate the bad ones by the amount of spam entries they have – they are not monitored, and will not be useful.
