» Between 1897 and 2009, 32 separate sets of sleeping guidelines for kids gradually suggested that children get less and less sleep — at a rate of about 0.71 fewer minutes each year. Despite this, parents over the year managed to fail at these declining expectations, with children getting on average of 37 fewer minutes of sleep each year. Why’s that? Depends on the era — at the turn of the 20th century, it was artificial light, radio and cinema; in the ’90s, it was video games, cell phones and the Internet. Let’s update these standards slightly: We blame Twitter and the iPad.
» On the plus side, that number’s falling: Between 1990 and 2008, roughly 7.3 children and teens per 100,000 fell out of windows each year, which is actually down — especially in areas that have pushed safety campaigns to prevent this from happening. However, it’s not the case in every city. In New York and Boston, previous studies have shown 96 percent declines. In this study, that level is much lower.
