Back to non-verbals
It's a bit of a cycle. We start out being non-verbal with Bright Eyes to combat his scripting and static behaviours. He improves dramatically in just a few days, and then it seems easier to go back to language with him. Over time, he reverts back to the scripts and we find ourselves going crazy again. We ring our consultant. She says, "Go non-verbal", so we do, and he improves... etc etc.
The best advice I can give anyone with an autistic child is to stop talking! Focus on facial expressions, gestures and tone. It really works!
