Thanks for your comment, @mhrose - kids ARE amazing! Now if only adults can learn to treat them like the capable, wonderful creatures that they are, the world will be a much better place. :)
The children love to be barefoot, play in the garden, climb trees, and dig in the dirt. It's true that exposure to soil has so many beneficial microorganisms, and they're also getting super healthful fresh air and sunshine! It's so incredible to see how healthy children can be!
