DS is just going into Y2 so I'm looking at what covers, say, Y2, 3 and 4. If we end up HSing I feel that knowing what's on the NC would at least give me a starting place - as much as anything to be able to show ex-h that I was making sure that DS was "learning" at least as much as he'd learn in school.
I understand how HE differs and it's not as simple as this, and the NC will essentially cause more problems than it solves, but in our situation (DS being the product of divorced parents with an unsupportive ex, although fortunately a wonderful and fully supportive step-dad) we don't have the flexibility that we'll have with DS2, who is fully "ours".
