I have worked with SN a few times...
We were able to remove children from the classroom IF they were a danger to themselves or others.. one little boy was trying to throw his chair... so WAS taken out kicking and screaming... I was there and to be honest, there was no reasoning with him, and would of definatly harmed others... explaining to a parent their children were hurt because we "let" a another child hurt them is just as awlful as dealing with a screaming angry autistic child who cannot understand or calm easily...

But it certainly doesnt sound like little W was in need of "restraining"!!! I too would be quite pi$$ed off babe... there is no need to touch, or remove a child unless there is immediate danger to anyone. Poor W, she shouldnt of done it, and it probably scared him and made him harder to calm down ... she definatly needs a talking too, esp if she will have regular contact with W... big hugs babe... xoxoxo
