I'm in the process of choosing for the first time, so I can't teach. I'll just commiserate and share where we are. After going in circles over a few different options (there's too many to look at all of them, since we aren't tied strictly to one style), I finally had to make a list of the ones I knew weren't right for us as first-timers, or based on our daughter's needs. And I added little notes about why they weren't the right choice for us since I was getting confused as I read so many reviews and threads on forums.
I also have a Google document where I make note of potential plans so I can quickly share them with my husband and get his input. I put the potential negatives down about the choice and how we can work around it. I hyperlink the doc with the threads, reviews, articles, or websites that helped me. And I note where the resource can be bought, too.
I love that! Every time I get overwhelmed I come back to a similar thought from a someone I know who was public, private, and home-schooled. It's not the curriculum or the school that was most important. Someone teaching strictly a curriculum isn't a teacher (this is a comfort to a school teacher friend that is wrestling with a weak curriculum). Intimidating, since it'd be nice if the perfect curriculum would solve our problems but as we know the programs don't do the heavy lifting and that's why we love good teachers. Still, we're thinking very carefully about the choices. We've seen some that clearly don't fit for us, but work for others.
