Here’s a quite amusing article about bringing up kids from a mother who let them play as they wished, turning off the TV and saying to hell with organised activities.
A few years ago, one of my daughters, who was happily and healthily bored, was outside coloring the bark of a tree red with Kool-Aid powder mixed in oil. Kool-Aid is a wonderful permanent dye that I suspect may color-fossilize the small intestine of anyone who drinks it. Kool-Aid stains never go away. If I ever got into tattooing, I would consider using Kool-Aid powder to mix my pigments, seeing that my mom has a Kool-Aid stain on her counter top that I put there 25 years ago, which has proven itself immune to bleach.
