PL is the perfect intro for 6. We then tried Minimus at 7 and while it's fun and did engage her, it wasn't a step by step intro to the language which her logical mind and my non-Latin mind needed! It quickly lost us and left us wondering why they were using certain endings some places and not others, etc., with little explanation. We're now in Lively Latin, which is AMAZING-we love it, and we will add in Minimus for fun sometimes. With upcoming ds almost 5, knowing what I now know, I will do Prima at probably 6.5, Lively a year or so later.
