My ds is 10 has autism, sensory issues, and ? ADHD He is VERY literal told me in the car on the journey home from school today ' A boy at school called 2 boys, a girl, and me retards' I said were you sad 'No it's fine I called him a leotard Mum!' He had/has no idea what 'retard' means I told him it's not a nice word, and he is NEVER to say it.
