Children throw tantrums when they want something and do not get it. By acting out, the child may hope to get what they want in the end. If you give the child what they want (e.g. ice cream, or a delayed bathtime/bedtime), then the child will learn that tantrums are a good way to get things. It is much easier to start addressing tantrums when the autistic person is a child. For example, a 6-year-old boy who throws himself on the floor is much easier to manage compared to a 16-year-old. Also, the child will be less likely to cause injury to themself or others. Planned ignoring can work best for yelling, swearing, and sulking. This will teach the child that the behavior is not an effective way to get attention. It helps to clearly communicate this idea, such as "I can't understand what's wrong if you're pouting back there. But if you would like to calm down a little and explain what is wrong, I would be happy to listen to you." Always step in if the child begins throwing things, taking things that belong to others, or hitting. Ask the child to stop and then explain why the behavior is not okay. Tell your child that they can choose to act in a way that will get the desired response. Explaining this to your child will help your child understand the best way to get what they want (or at least a listening ear or a compromise). For example, you can tell your child, "If you'd like me to help you, you can take a few deep breaths and tell me what's wrong. I'm here for you if you need me."
Consider how your actions can affect your child's tantrums. Address tantrum behavior early. Ignore tantrum behavior. Intervene if the child is being mean or doing dangerous things. Invite your child to behave better.
