Parents must be aware of child’s need of verbal development through various strategies. There are several ways to develop verbal skills in non-verbal children.
It's not true that all children on autism spectrum are socially disconnected. They do struggle with social skills but that is because they are unable to communicate their desire in the very same way you do. They may seem shy or unfriendly.
