In Italy, pregnant women are likely to enjoy a glass of wine once a week. In Japan, sushi remains a staple for dinner even during the third trimester. In America, women are told over and over again that these items, and a laundry list of others, must be restricted during pregnancy. Economist Emily Oster breaks down the typical pregnancy recommendations with data-driven research in "Expecting Better" to provide women a better understanding of the choices they can make during pregnancy. Oster's latest book, "Cribsheet", weighs the pros and cons of sleep training, breastfeeding, and the many other decisions parents have to make during early childhood.
