Going to a restaurant:
Before you leave to go to a restaurant tell your child where you are going and what is going to happen at the restaurant. Just give your child a brief overview of what a restaurant is like and what you do there. Bring a reinforcer that will keep your child busy and occupied. Make a picture schedule/outline and let your child where you’re going and what you’re going to do.
Once at the restaurant use the schedule to guide your child through your meal. Praise often for good behavior. If your child is having a hard time try to make the meal as short as possible. Start with a fast food meal and then move on to a sit down restaurant. Going out to restaurants might require a lot of practice. Take your child out as much as you can and start them young. Habits learned form little on will become easier for children with autism to deal with.
