In high school and college, I was thin and wore a D cup, which, quite frankly, did not bother me a bit! When I started seriously working out at age 25 or so, I went down to a C and became leaner overall. Then I had my first child at age 30, breastfed him for 14 months and went down to a B. I also got much thinner and no matter how much I ate, I couldn't keep enough weight on. Three years later, after breastfeeding my second child for 18 months, I lost even more boobage. Five years after that, I breastfed my third child for 2 1/2 yrs, discovered Cathe, and now, at 42, I'm barely a B! I also think I'm too thin (except my stomach). I wish I'd get SOME of my old breast size back (sigh).
