My 18 year old has developed OCD type behaviour, alongside his autism, which manifests in his constant questioning / seeking reassurance for very minor incidences. For example, if a bird flies away when he walks past, he wants to know if he has done something wrong. He has a ritualistic way of having to be reassured. When I say constant, it can be up to about 30 times a day. Has anyone else come across this and how do you deal with it??
