In reference to Twig's OP, just wanted to say that my children are home educated, but I don't have them with me 24 hours a day.
They have art classes, literacy classes, music lessons, they go swimming, do karate, stay over at their friend's houses etc - just the same as children who go to school do.
They also go to home ed groups during the week, as well as to educational visits.
Home educators don't have to follow the national curriculum - which is one of the best advantages of home ed IMO, as the national curriculum offered very little to my children.
Offering a total curriculum is not as hard as it might appear, as their learning tends to be topic based, rather than half an hour of history, half an hour of geography etc.
Since being home educated my children have taught themselves to be independant learners.
I work from home, so mornings are spent doing their maths and literacy work, with me available to help if required.
We usually go out in the afternoons and evenings.
It is tiring, and can be stressful (I feel VERY responsible for their entire existence at the moment, and have a constant niggle of self-criticism in my head!), but the positives far outweigh the negatives for us.
