I think we've moved to thinking of parenting and pregnancy as something in which you should lose yourself.
For many women - myself included - pregnancy brings on tremendous anxiety and confusion, along with the joy.
Almost every woman I have spoken to about pregnancy has a story about her doctor giving her a hard time about her weight. Later in my pregnancy it felt like all of my time with my doctor was focused on how fat I was getting - so fat!
The biggest food-related risk in pregnancy is listeria. It's a dangerous bacteria, to which pregnant women are especially susceptible, that can lead to miscarriage or stillbirth.
Nausea is a normal but unpleasant effect of pregnancy and a really good sign that it is going well. Women who experience nausea in early pregnancy are less likely to miscarry.
I think that there's a real sense in which pregnancy should be something that you do with your doctor, but I think that for a lot of women the time you have with your doctors is limited and it can be difficult to get all of the answers to your questions.
