I hate actual cirriculum for little ones. I prefer to let them pick out at the library what subjects they want to study that week and then get books made for their age group on those subjects.
When I was in highschool my parents took me to a homeschool store and let me pick out my books. I never used one brand. I learn differently in different subjects so I would look at them all and pick the ones I could comphrend the best. This method worked great for me and I guess that's why I'm using the same method with my kids. At their ages I'm still picking the books, but they are both under five years old.
