I once asked your same question on this forum, and beloved members recommended "How to multiply your baby's intelligence". The reason is that the book summarises the entire math, reading, and encyclopedic knowledge (EK) programs in one book. So if you can get this one, you may not need the seperate reading, math, and EK books.
My next choice would be 'How to teach your baby to be physically superb'. This one is for the physical program (from birth to age 6). And there is another one called 'How smart is your baby (this one contains the physical program from birth to age 1).
So, in summary, my choices would be:
1) How to multiply your babies intelligence (for reading, math, and EK programs)
2) How to teach your baby to be physically superb (for physical program from birth to age 6)
3) How smart is your baby (mostly physical program from birth to age 1, though some reading strategies (use of flashcards) are also included.)
Here was the thread where I asked the question (
http://forum.brillkids.com/teaching-your-child-to-read/question-about-doman's-'teach-your-baby-to-read'-book/msg77634/#msg77634).
And I never prepared Doman flashcards. I used LR. Plus LR has a print function where you can simply print out the words. And for Doman math, I never got math flaschcards either. I simply used LM.
