Claire, what ages are you looking for?
Lively Latin I know nothing about. Getting Started with Latin is a TERRIFIC beginner program. It really doesn’t get you very far, but it is a very good starting place. Started there with my third son.
I’ve never used Latin for Children, although I have used Spanish for Children. It is a solid, steady program. Not as many reading type things in it, which I do like.
Latina Christiana is supposed to be good for younger students. Again, it doesn’t go very far, you will have to move to another program at some point.
Henle has an excellent reputation, almost as good as Wheelock’s, and I think it doesn’t move quite as fast. It’s very tradiitonal–written a long time ago. Memoria really likes it, if I remember right. It is an upper middle school/high school program. Very serious on grammar.
