Who knew three kids could "need" so much for homeschooling? I sure didn't but I promise we use it all or I wouldn't keep it. I have most of Big Kid's curriculum for the next year or two, because I fell across it at a homeschool book store that was closing. That takes up space. I have some K and 1st grade curriculum for the twins, someone gave it to us, and who knows when they will actually start using it, so I keep it handy. Everything else is used on a regular basis - wow!!
I love the new bookshelf - it brightens up the room and stores everything we need in that room! I have a bit of extra space on the shelves, hopefully we can keep it that way. I honestly don't have to buy any curriculum for Big Kid until 9th grade, but I really don't know what I'll need for the twins as they grow because I have never homeschooled a child younger than 6th grade! It's an adventure :)
