I’m going to jump off course for a minute, and suggest you read Charlotte Mason’s Vol. 6, A Philosophy of Education. This will give you a better idea of why you are doing what you are doing. It’s not so much about which curriculum, but why and how you are implementing it. Like sarah2106 said, you can truly start/stop anywhere you want.
I don’t mean this to be snarky 😛 However, I have learned over the years in jumping around that the grass is not greener. Once I had a better handle on Charlotte’s philosophy, it helped me to see truth. I’ve used both SCM and BF and either one is great.
No matter which program you use, be sure to view your child as a born person and expect narration. These principles alone will carry you farther than a particular history rotation. 😉
May you be blessed in your decision,
Melissa
