I agree.
Though Autism is a huge spectrum and less the 30 years ago those who are higher functioning who have jobs and families wouldn't have been recognised as having a disability.
Certain autistic traits can include unhealthy obsessions which include restrictive behaviours and obsessive reactions.
My DS is also autistic without learning disabilities he has a very high IQ.
My neighbours child is non verbal and enjoys licking and touching people, even strangers, he is 10, he took a liking to one of the DC on the street and he'd have a breakdown when she ran away he wanted to hold her and lick her.
He is not allowed out anymore because he is very strong too.
I am very conscious about DS and how he develops an interest in certain things or certain people and I have worked very hard teaching him, still not there yet.
I have thought about his relationships in the future, he is controlling, aggressive, repetitive and doesn't think about anything outside his own needs first.
The reason people recieve DLA/DCA for a child with ASD is because they need more care and sense of direction in RL.
