At my sons’ private boy school there was a wonderful young man who suffered a serious disability. Could not play sports: so he was team manager, and very much a part.
Look for alternatives. It is part of the pain, but the reward is so much deeper than what the typical kids’ accomplishments bring.
I’m not for government involvement, but I am for speaking up for kids.
I actually think getting the government involved might hurt the kids in the long run. People without disabilities resent being forced into helping.
My daughters go to a private Christian achool, and you would think they would be more helpful.
