Stimming – or self-stimulatory behaviour – is common in children and teenagers with autism spectrum disorder (ASD). It usually won’t harm your child, but it’s normal to worry about how it affects your child’s learning and socialising. Skill development, environment changes and behaviour strategies can help.About stimming and autism spectrum disorderStimming – or self-stimulatory behaviour – is repetitive or unusual body movement or noises.Many children and teenagers with autism spectrum disorder (ASD) stim and might keep stimming throughout their lives. They use stimming to manipulate their environment to produce stimulation, or because they have trouble with imagination and creativity and can’t think of other things to do, like pretend play.The amount and type of stimming varies a lot from child to child. For example, some children just have mild hand mannerisms, whereas others spend a lot of time stimming. Stimming might include:
Stimming isn’t necessarily a bad thing, as long as it doesn’t hurt your child. But some stimming can be ‘self-injurious’ – for example, severe hand-biting.Stimming can also affect your child’s attention to the outside world, which in turn can affect her ability to learn and communicate with others.For example, if your child is flicking his fingers near his eyes, he might not be playing with toys so much and not developing his play skills. When he’s older, if he’s absorbed in watching his hands in front of his eyes in the classroom, he’s not engaged with his schoolwork. If he’s pacing around the area in the playground, he’s missing valuable social opportunities.We all use stimming sometimes. For example, some children suck their thumbs or twirl their hair for comfort, and others jiggle their legs while they’re working on a difficult problem or task. You might pace up and down if you’re anxious, or fiddle with a pen in a boring meeting.Why children and teenagers with autism spectrum disorder stimStimming might happen because children and teenagers with ASD are:
Helping your child with stimmingStimming often reduces as your child develops more skills and finds other ways to deal with sensitivity, understimulation or anxiety.But there are also several things you can do to help your child with stimming.Changing the environment If your child finds the environment too stimulating, she might need a quiet place to go, or just one activity or toy to focus on at a time.If your child needs more stimulation, he might benefit from music playing in the background, a variety of toys and textures, or extra playtime outside.Some schools have ‘sensory rooms’ for children with ASD who need extra stimulation. There might be equipment children can bounce on, swing on or spin around on, materials they can squish their hands into, and visually stimulating toys.Working on anxietyIf you watch when and how much your child is stimming, you might be able to work out whether she’s stimming because she’s anxious. Then you can look at your child’s anxiety and its causes.For example, is there something new or changed in your child’s environment? Preparing your child for new situations and teaching him new skills to deal with things that make him anxious can reduce stimming.Encouraging physical activityPhysical activity might reduce stimming by getting your child engaged with others and keeping her occupied. After exercise, children can often focus better on their work. If your child is engaged in her work, there’s less motivation to stim. You could try short sessions of physical activity throughout the day, to break up other activities.Using behaviour strategiesYou could try these behaviour techniques to help your child with stimming:
