It has been statistically shown that people who struggle with neurological disorders are much more likely to self-harm, relative to those who are “neurotypical”. Please make yourself aware, be calm when you suspect it, and talk openly in a caring and accepting way. If you make a big deal of it, your child will hide it. Let your child know that it is another symptom of their disorders, and that you are going to support them with this, as you do with the other symptoms.
