Yes, your question is very clear and I think many people are thinking the same thing (like me
)
The new version of LR (Little Reader v3) will be releaces early this year. It will have a functionality to select the catagories you want to teach as a course and then automatically generate a course for you that will be similar to the Brill Kids courses, I'm guessing that it will rotate and reapeat as the days go by to aid memory. (Glenn Doman describes in his book that a good set has familiar and new elements, so then the child feels encouraged because there are things he knows well and feels intereted because there is something brand new too.)

Personally, I've decided to translate the BK catagories to the two languages I want to teach additionally, and then wait for LRv3 to come out to build courses before I start with these translated catagories. I plan on spacing them out 3 months between each course, because I think it will make it harder for my child to learn the exact same word in 3 different languages at the same time.
All the best and good luck with Arabic, it sounds tough!
