I really WANTED to like the Sonlight curriculum. I love the books and the ideas behind it, but the problem for our family was in making it work each and every day.
It simply took took much of my time to spend with each child every day and I became exhausted. It is a time-consuming program to learn to use and execute.
My kids are spaced apart too much in age to use just one Core program for all the kids, so I spent four hours with two of the kids and then had to do it again with the next child.
If you only have a couple of kids close in age, or older kids who can do it more independently, this curriculum might work well, but it didn’t work for us. (BUT I did keep the books for reading…they are great!)
