Just a caution:
This year was my first with TOG. I don't know anyone personally who uses it, just read great things on this forum about it and thought I'd love it too.
I think I would have liked if.....
I had not tried to do so many things and
If I had not tried to use so many books.
I way over scheduled and it made for tons of stress between the planning and trying to work it all into our day.
Remember that it is a buffet and choose to do what will work for your family. If you don't mind planning your days from the choices that are provided it will work.
That being said, I am planning on using something different in the fall....less planning on my part will work better for us.
