I too nursed, four years each girl - the first year I lost the weight, my boobs were incredibly flat like pancakes - it was really horrible. The skin would wrinkle like a brain, just a complete and total lack of collagen. I have been taking a collagen supplement, drinking bone broth as well as using Emergen-C with MSM and using lotion and things have really changed a lot. The skin has sprung back a lot, no more "brain" lol. I'm quite relieved! I did lose the first 90 pounds very fast - in just 8 months. That might have something to do with it.
