Just wanted to say that comments directing the OP to put her children in school are really out of line, and reflect a real bias against homeschooling. Even in cases where a parent is depressed, school isn't a quick fix. It creates new stresses and time demands. I would no sooner tell someone posting in the Gentle Discipline forum to put their kids in school than I would tell someone to quit breastfeeding.
As much as I believe in breastfeeding, there are times when I would give someone this advice. I don't think homeschooling is always the best choice. People mention school because it's a source of evaluations, childcare, and other services. If school is the best wasy to access those services, I think it's worth it.
