Well, I found the answer to one of my questions from yesterday in another thread. I found Carrie's own schedule for doing Bigger half speed, and that looks like a great way to start the new guide with Pete, my reluctant writer.
But I'm still stuck on how to combine him and his sister for the "inspirational subjects"--History, Bible, Music, etc. She is already participating with us in those subjects--listening in and doing what she can or what she has a mind to.

I would hate to lose that "together" time. I had always assumed that because of their age difference and because I started Pete on the young end of LHFHG that they would always be in completely separate guides, but we're falling into a natural rhythm of half separate, half together. I'd really like to keep it that way! Reading and talking and praying and singing with one kid snuggled upon each side of me--that's the best part of my day!
