You're not alone. I've posted 3 schedules on my blog this year. I'm constantly tweaking. And no, I don't stick to it perfectly. For instance, we traveled over the weekend and did lots of driving. One of the kids threw up just before we left and I needed a little recovery time Monday morning so we ditched math and language arts for the day and just did our reading. Wednesdays are pretty much the same because we go to CBS and I count the kids' homework as their language arts. Fortunately the kids started the year ahead in math so it hasn't hurt us. One of the things I love about homeschooling is that I have the freedom and flexibility to ditch the schedule when something more important comes along. Now, we're expecting snow here tomorrow and I've already told the kids that even if they cancel school, they will have school as usual, so I guess it works the other way, too.
