Many children with ASD do not feel the need or motivated to communicate as everyone in their environment thinks for them, gives them what they want or even anticipates their needs. When you create a communication programme it is VITAL you create as many opportunities as possible for the child to communicate.

Encourage verbal children to use their words or extend their word i.e. “Drink” to “I want drink” and non-verbal children to use visuals/signs/gesture to communicate.
