The craziest part about back to school for me is that my niece and nephew in Arizona are ALREADY back in school! They went back on Monday. Crazy. It's not only the students who are stressed about going back to school, almost six in 10 parents are so worried about their child that they've lost sleep in the back-to-school season. A survey of parents of school-aged children (aged 5-18) revealed that 57% find the back-to-school season to be the most stressful part of the year!
