Just throwing this out there...;)
My dd was like that when we first started hs'ing. Every.single.day there were tears and tantrums during school to the point I really thought something was wrong, but for her it boiled down to the fact that I wasn't using things that were appropriate for *her* learning style. I bought things that appealed to *my* learning style. I wasted A LOT of $$ on SL and WP b/c I totally love a literature approach. Dd, however, did not. She is (gasp) a workbook kinda girl. If you start reading to her she just falls apart; eyes glaze over, etc.
It took several years for all of this to click in my head. I assumed I was just a rotten teacher, or if I could just buy the next popular thing, etc. I actually had to step away from hs'ing boards in general b/c I always felt like my method of workbooks/textbooks was frowned upon. And some would frown upon it-but I really don't care. :) I now have a dd that LOVES school and who is often at our hs table by 8 am, ready for the day, and ready for her workbooks.
Just a thought. :)
