I had a friend who regressed back into her bulimia while she was pregnant (she had a lot of emotional issues and a history of incest and being pregnant brought a lot of those issues back up for her). When her little boy was born he had a normal size skull and a weeny scrawny little undersized body. It was heartbreaking to see. I agree with BG, this is a separate and different issue to the pressure brought to bear on women by the media, other women etc.

Having said all that, many women are unneccessarily harsh on themselves and their self image during a time when their bodies are simply following a biological imperative. We are often prone to unfavorable self-comparison with other women, and yes those images of personally-trained, stylisted celebs do not help. But you can choose not to consume those magazines/tv shows, etc and read healthier, more empowering material instead.
