Growing your own vege and fruit, is such an important skill to have, particularly now, when so much of our food is contaminated with toxic chemicals. It is great to see kids enjoying gardening, and not seeing it as a chore, but something that is fun, and rewarding.
I think the work that Stephanie Alexander is doing, is of great benefit to children, and adults. At least some of this generation of kids, will know what real food tastes like, and hopefully they will take the skills they learn at school, into their adult life.
Your kids are so lucky, they get to learn at home :)
