Hi my daughter is 5 non verbal and severely autistic. She has started to be totally upset with visitors coming to house - cries entire time until they go, tries to push them out of door. pretty much isolated going to anyones house as she gets too upset. Loves going to school. Horrible seeing her so upset but getting to the point cant have anyone round which was not very often antway! Any tips or advice thanks. She has her own space in house but wont go there
