Here's one thing that I cannot tell you to do as a SN educator/professional. I cannot tell you which school to go to (mainstream/SPED) for your child. At the end of the day, parents make the inevitable choice of choosing the best option there is based on the support that your child needs. Even though I basically kinda alr know as his teacher which path your child should go. I can only hope that with acceptance comes the best decision making for him/her.
