I had Post Partum OCD. I wish I could say it went away but the second child didn't help it go away, it stayed about the same. If you don't want meds or want to support what you are doing already I would try this MP3 download. You just listen with head phones in bed at night and it really helps. They have a whole series of other MP3's as well for Hypno-birthing in case you decide to have a second baby and many more including depression,etc.Check it out.
