Mistake: Allowing too much screen time

Like to park your kids in front of the TV? Bad move. Anything more than two hours is too much as far as screen time goes, particularly for kids two to five years of age, according to the report. This includes cellphone and computer screens as well as television. In addition to making kids sedentary, screen time means they're exposed all sorts of ads for less-than-healthful foods and beverages - a weighty-kid double whammy.
