I think most women who have babies have a post partum experience that may or may not end up being a true depression or psychosis. I think more women end up with "baby blues" but I like to call it post partum experience just because I feel like that makes it seem less like an all or nothing thing--you're fine or you're not. The bottom line for me is that this is a time of major upheaval in many ways and often a lack of sleep goes along with it, and the effects of sleep deprivation should never be underestimated. It takes a physical and mental toll. I think our whole model for pregnant, birthing and post partum mothers is way off of what the ideal is for us to be as well as we can. Look at the way pregnancy and childbirth are handled by the majority of people in this country, and then combine that with this idea that after we have a baby everything is supposed to be just as it was beforehand. Given the hormonal changes as well as the "OH MY GOODNESS, SOMEONE JUST GAVE ME A BRAND NEW PERSON WHO IS COMPLETELY DEPENDENT ON ME" aspect of things, we are going to have some post partum issues.
Now a true clinical depression or psychosis that occurs in the post partum period is different. I don't want to downplay the seriousness of that, but I think the true psychotic breaks are rare and there is a lot that can exacerbate that too.
The problem I have is this approach that is not nurturing or holistic at all (and I am pretty mainstream on the medicine front) but is just like, "Oh, you feel that way? That's a disease, see a doctor." I read an interview with Brooke Shields in a magazine about her battle with PPD and I really was unhappy with the article. She would talk about she was feeling and how wrong it was and can you imagine someone thinking that and I was like, "yes, I can, I had some of those same feelings! A lot of women do." It just seems like the whole look at this brave woman coming out with the truth about her life is not perfect is surreal, and it is trying to make pathological aspects of our natures and experiences that divides us even further from the kind of support we need.
