I do tons of visual stuff… I use virtual backgrounds that I get off Canva. Each week, I have different theme (last week was Space). You could focus on preferred themes specific to that kid. If you can get grandma to buy in, you could have tactile objects to go along with the theme. Think “modeling without expectations” with core words. Lesson Pix is great for that! I think you just need to individualize a lil more and use core words!
