I breast fed my second child for 10 months. About a month after starting to wean her, postpartum depression hit for a total of 3 months. My OB-GYN as well as my primary doctor said there was nothing wrong with me, but I lived through panic attacks that were beyond imagining. About 15 years later, I read an article in a woman's magazine that explained the experience to me: I was coming down from an estrogen high. Postpartum CAN occur months after giving birth!
