We've used it sprinkled in with SOTW. I loved FIAR and if my girls would dive into the research themself I would love BY, but I feel like it was taking a lot of time for ME to plan. I will still probally use a few more books this year but I couldn't do it all the time. We like it as more of a break from something a little more structured. Some families love it though. You should check out the FIAR forums for more advise. :001_smile:
