A friend of mine ACTUALLY sent her husband to a hearing clinic. When they asked him why he was there, he said "My wife says I can't hear her." They thought that was pretty funny - and no, he had no hearing issues.
Anyway, on topic again, I just don't think two different grades is, like, even an option these days. It's more like regular ed/special ed, ya know? But seriously, if you're talking about a 22 month old who doesn't hear you when he's busy and has a REALLY shaky understanding of the word "no," in my totally nonprofessional opinion what you have is a 22 month old. Just sayin.
All that said, if you have concerns there's no reason not to bring them up to DS's therapists, they are more than likely hooked into the larger educational/therapeutic system and they can give you a broader perspective.
