One complication of this behaviour is that there’s no set way to respond; what works for one family may not work for another.
Before implementing a strategy for your child you need to understand the triggers for their behaviour.
Are there particular places, events, or objects that the child responds to violently?
Most children are sensitive about certain things or get stressed about certain events. With disabled children, this sensitivity can be enhanced. For example, sensitivity to loud noises, bright colours, or certain textures. Understanding what triggers the child can help reduce the behaviours by removing or reducing the trigger where possible. It might help to keep a diary for a while. The Challenging Behaviour Foundation have a chart which you can use to record your child’s behaviour here.
Are environmental factors involved?
Consider whether the child’s environment might contribute to their behaviour. If violent and aggressive behaviour is prominent in a certain place, for example at home or at school, then you may want to look at ways of modifying the environment to help them.
A common problem can be sensory stimuli in the environment such as noises, smells, and colours. For more information on sensory needs and what changes can help please see The National Autism Society’s website.
Could your child be experiencing pain?
If the child’s behaviour changes suddenly, then it may be due to physical changes your child is experiencing, for example, puberty pains or a toothache. If your child finds it difficult to communicate, it might not be easy for them to tell you about their pain and difficult for you to know what they are experiencing. Some children struggle to recognise the signals from their body so it can be hard for them to articulate that they are experiencing pain and some children do not have the verbal ability to express themselves. PECS cards can help children to indicate that they are experiencing pain.
Has there been a change which might have triggered the behaviour?
Changes to a child’s routine, in who is providing care to them or changes like a new baby in the family can spark challenging behaviour.
To help your child you might want to consider using a social story to explain any changes to them in a way that helps them to understand. If you can, try to use social stories to prepare your child for any changes that you know will happen.
