We have come to a few conclusions:
- This is one of the very few things he controls (along with the eating). So it has to be under his conditions before he'll choose to say words. He does have a large vocabulary, but if you ask him to say something, he won't (he can, so it's not apraxia or anything like that) because he's choosing not to.
- For a child with a neuromuscular disease, he moves a LOT. Speech Therapist thinks that he is concentrating on that at the moment--when children learn to walk or crawl oftentimes the vocalizations will cease somewhat until they get it down--they can't do two things well at once.
- He is constantly surrounded by people who cater to his every whim, so all he has to do is grunt and look at whatever he wants and he gets it (not a great thing, but as he can't get toys, etc. himself that's just the way it has to be).
So, we (Speech Therapist and I) have decided that he will talk talk whenever the heck he feels like it, the same he did with the eating issue. I think the key here, though, is not to force him or fight him about it, as he proved with the eating that approach does. not. work.
Boo. I really want to know what's going on in his head. Guess I'm going to have to wait.
