A recent study appearing the the April edition of Pediatrics, due out today, reports a new finding on the trend of childhood obesity in America: that many US children are too heavy for their carseats. Parents who are uninformed about this problem will likely continue to use the wrong carseat, as will those who have trouble admitting to a weight problem in their children. Carseat makers are releasing new carseats with a higher weight limit (one is called the “Husky”), which is an important stop-gap measure. But this study is just one more indicator for the need to turn off the television and get children actively playing and away from commercials depicting junk food and sodas.
