Thankx @tsc for the link. He doesn't always recognize pictures unfortunately. I have flashcards with pictures, numbers, animals etc and he struggles. But then he surprises from time to time and will recognize a word that he sees and will say it out loud and it brings me much joy. He has primary progressive aphasia, so ALL of his communication skills are affected... from speaking to understanding what is being said and being able to read, even the basics. So I use alot of gestures and pointing to help him understand. I have several children's books that i keep laying around and he seems to enjoy them as much as he can. He'll open them and he'll interpret them they way he sees it and THAT brings me joy as well cuz he's trying and not just living in a world of silence.
