Yes, they do. There are a correlation between the mothers eating habits and damages to the fetus, especially when it is a lot of fat and little micronutrients and vitamines. The risk of diabetes, heart disease, fatty liver and enlarged heart are also increased in babies born from obese mothers.  This is why the whole #mybodyisNOTbroken debacle infuriates me to no end. Just because you MIGHT be capable of getting pregnant doesn't mean you should, especially when you have a body so unhealthy it will damage you child from the moment of conception. Why the fuck are these white, middle class sows so incredibly selfish and irresponsible?
