I love Emily Oster‘s parenting books. She‘s an economist and uses research to make her parenting decisions. Her children are slightly older than mine, so each time she releases a new book my kids are the perfect age for the content. I‘ve followed her since “Expecting Better”, my favorite pregnancy book. This one is for school aged kids and covers topics like, when to get kids phones (12!), redshirting kindergartners & extracurricular activities.
