Just after some advice. DD 6 is in mainstream school. Diagnosed with asd. School seem to be struggling with her behaviour and yesterday in a meeting with the senco it was suggested that my daughter may have ADHD. Now I know nothing about ADHD other than it has a bit of a stigma (sorry really hope I don't offend anyone this is absolutely not my thoughts just from things I've heard/read) that I'm worried about her being diagnosed with it. Will it make a difference? If she already has an asd diagnosis will an ADHD one make any difference as she already receives help? Basically wondering if an extra diagnosis is needed?
