Breast Feeding

I'm Curious As To Know If Breast Feeding Can Actually Make Your Boobs Sag ? I Have Always Heard Rumors About That But I Mean Some Women Are Different So Breast Feeding Turns Out Different For Any Woman. I Wanna Breast Feed My First Baby For Sure But I Just Wanna Know The Pros & Cons Of Your Experiences. Mainly.. Can Your Boobs Become Saggy ? ._.
