There’s an old saying: “Prepare the child for the road, not the road for the child.” But these days, we seem to be doing precisely the opposite: we’re trying to clear away anything that might upset children, not realizing that in doing so, we’re repeating the peanut-allergy mistake. If we protect children from various classes of potentially upsetting experiences, we make it far more likely that those children will be unable to cope with such events when they leave our protective umbrella.
