Autistic boy denied communion because he can't confess his sins

Under the definition in the Bible for sin, the boy cannot sin and does not need the sacrament or anything else for the forgiveness of sins. Is forcing a child with a profound cognitive disability to eat a dry, tasteless wafer and take a sip of what the child will certainly feel is very unpalatable wine an act of inclusiveness, or low grade abuse?

I'm a retired special ed teacher. This is not about the kid, this is some kind of self indulgent hissy-fit being thrown by the parents.

After watching and reading an earlier post by another RPer being offended that some non-Christian witnesses refused to say "So help me God" during their swearing to tell the truth in a hearing, I wonder how he would feel about this?
