What do you mean by "constantly forcing a toddler to do something s/he doesn't want to do", Beowulf? Is it "forcing" to require him to eat healthy foods when he wants candy? To providing him with mittens in the winter and insisting that he wear them outside instead of tossing them? To fix a specific bedtime, to request he bathe and brush teeth even if there are other things he wants to do? Is it forcing if you get his agreement with negotiation? With explanations. With as much comprehension of the benefits as is possible at a particular age?
I would never use violence on a child, whether physical or emotional, but I sure would work very hard to convince a child that there's a very good reason to wear an HA -- if that was a critical part of the educational and communication path we'd developed AND we knew it was providing benefit. And I did exactly that, worked with my child to use her HAs until she, and the results of her testing, made it clear that she was not getting any benefit AND there was no future benefit to be had from them. And then we changed plans. Persistence yes, but not "forcing" as far as I'm concerned.
Similarly, if Li suddenly refused to use ASL one day (as several deaf toddlers WITHOUT aids or CIs in her classes have done, to the chagrin of their Deaf families), I would not give it up and say -- well then, that's that, a toddler's decision has been made. We would try again repeatedly, working to find a way to make it fun, to find beneficial results that she could recognize upfront. This is NOT child abuse.
