If you are really that freaked out about it, then why not try a relaxed approach instead of unschooling? You could focus on several things per day, then let the kids have the rest of the day for "unschooling". You really didn't say much about WHY you are freaking out and panicking... If this doesn't feel right, and you are not 100% behind it, then maybe you should ease into it. Homeschooling/unschooling should be at least tolerable for the teacher/mother if not fun.
