When you start that lingerie company I'm there with you. I went from a full B to a small BA after breastfeeding my first two. After I finish bf this one who knows where I will wind up. I can honestly say that I felt a lot better about my size after nursing my first two babies because I felt "womanly" in the best sense of the word - my "underdeveloped" breasts did a great job. That being said, I would get augmentation in a heartbeat.
H hates that I feel that way. He believes that people shouldn't mess around with God's creation. Blah! Blah! As I have gotten older I have learned to be proud of my body for what it can do - have sex, bear children, nurse, do karate, run etc... Breast size feels like less of an issue now. If I got surgery it would be so that clothes fit better, so that I had a more flagrantly sexy look to enjoy etc... Anyway, maybe someday I will. Maybe, I won't. I can be sexy either way (BTW - a random 20ish guy told me so the other day - I was walking my baby in her stroller and he said, "You're cute and your baby is too). Not bad for a 37yo Mama of 3 with small boobs!
