The internet can be a great place, but we need to be aware of the risks involved with being online. For children with SEND, they may encounter further challenges and therefore additional support may be required. There is a lot of tailored information available to parents and carers and the following links are a great starting point:

The above sites cover topics such as helping your child browse safely online, setting appropriate parental controls, activities to help discussions about being online and the steps you can take to help protect your child online.
