Ds is 6. He goes to a mainstream school with 60 kids over 2 classes. In his class there are 3 children with 121 support so the class is busy. In the other class there are 2 children with 121 so overall 5 over the 60 kids. Ds and other kids have had some issues with violence towards them. The 121 staff I'm not sure if they're able to control the kid they support. Is it usual for the needs in mainstream to be so heavy ?
