I will leave the specific legal issues to those more expert in these matters than I am, such as co-blogger Eugene Volokh. But one example from the text was particularly striking to me, based on personal experience:
Even one generation ago, the norms were different for determining the age at which a child no longer needed a babysitter. The expected minimum age for babysitters has gone up as well, although in the few states that have legislated specific ages, the thresholds vary widely. In Illinois, it is illegal to leave a child under 14 unsupervised for an “unreasonable period of time”; in Maryland, in contrast, a 13-year-old is considered old enough not only to care for himself, but to babysit infants.
