Just in case you were wondering like me if indeed the speaking valve was still not an option for Theodore, wonder no more.
I tried it today since it's been over 18 months since we last tried. I thought surely he would do much better and that it was only my lack of attention to this matter that was stopping me from hearing my son.
It's all the same things as before that are keeping me from hearing him. So thank you, inflammation, scar tissue, and the like for being a pain in the arse. I really didn't want to hear him anyway.
