It's tough seeing other "special needs" kids look so much more normal than yours. I understand completely
. While I'm crazy for my own son, there are too many days where I wish he could feed himself/walk better/tell me what he feels. But he can't. His hearing is fine
It took me a couple of years before I realized that wasn't going to be a fix. Nothing could be done to give us the magic to make him catch up and be normal like the children everyone else seems to have so easily.
Next time put on your best sarcastic/incredulous face and tell the dolts "Oh my god - you're absolutely right! I'm going to tell the doctors to call you from now on... since you know it all."
That aught to shut their gobs.
