There is a need. At the SOGC, the Society of Obstetricians and Gynaecologists of Canada, we talk a lot about healthy pregnancy in general and making a package. Nutrition is important. Stress is important. Not taking drugs is important. Alcohol is important. It's a whole package of education around how to have a healthy pregnancy and a healthy baby.
You have to take the data with a grain of salt sometimes, because some women will report that they're drinking during pregnancy but they're having half a glass of wine.
