I have heard that postpartum depression runs in families. My sister had postpartum depression with both of her children, and now that I am pregnant, I am thinking it would be sensible to prepare for postpartum depression too. Of course, I am hoping that I will not have to take any drugs or have postpartum depression at all, but if it does happen, it is good to know what to do about it in advance. I have seen my sister struggle through postpartum depression for a whole year with her first, before she approach her doctor for help. I don't want to go through the same thing. What do you think is the best drug for postpartum depression?
