I've been sharing all submissions by posting them in a shared folder on our internal network. My own goal as a parent is not just to protect my children from their environments and vice versa, but to help my children outgrow me. That may sound sentimental, but it's also realistic.
All children outgrow their playpens.
More sophisticated playpens just produce more sophisticated escape artists. We have to work with, rather than against, our children's desire for freedom and autonomy so that, when or just before they can climb out of the playpen, they trust our warnings that some things are truly dangerous or hurtful, and not just off limits because we say so. Later, we even have to teach them to experiment directly with the world, to test our advice for themselves and learn things we couldn't teach them, without doing themselves or the world irreversible harm. Teaching fixed rules, but not the skills and judgment to test those rules or invent new ones, is irresponsible and ineffective parenting. And seeing the economy as an ecological subsystem is absolutely critical.
