I know I'll be glad to make my final decisions about next year- this back and forth is killing me!
I had the pleasure of talking with another homeschooling mother over the last few days and they are using Classical Writing. I toyed with this program last year and ended up not going with it, and here I am again!
I think it's a good, solid possibility.
I'm also looking at D'Aulaire's Greek Myths from Memoria. I think Sweet Pea would absolutely adore this.
