I went to see a specialist school the other day and this mum, who I made friends with brought her daughter along.
I could of sworn the daughter was autistic as when I said "Hello" to her, she didn't register me... Like she was in her own world and she had strong sensory issues, but the mother said she wasn't, just severely language delayed.
I just think wow, they must find it hard to differentiate between a severe language delayed child and a child with autism.
