It’s completely normal for kids to get 6-to-8 upper respiratory infections and 2-to-3 gastrointestinal infections a year, so you might want to give your boss a heads up now. You’re not totally helpless against the onslaught, though. Employ some of the basics, like frequent hand washing and sanitizing of toys. Encourage plenty of hand washing in your kid, too, and if they’re in a day care without a strict “no sick kids” policy, move them. With diligence and a little luck, maybe you’ll only have to miss work for 4-to-6 upper respiratory infections and 1-to-2 gastrointestinal infections a year.
