That is ME when my oldest was six!
I was such a curriculum junkie and I thought I'd never change. In some ways I haven't, considering everything we brought home from the library fundraiser sale and how excited I was to find a copy of Harold Jacobs' Algebra for $1 after giving up on ever being able to afford it.
Don't forget about thrift stores, borrowing books from the public library, and free internet resources in all of your excitement, though. My greatest regret about my curriculum junkie days wasn't the money I spent but the way my ego could get involved when something I'd saved up for and longed for just didn't make my kiddo's boat float.
Feel free to remind me to reread my own words if ds prefers a thrift store special to Jacobs later on in the coming year.
