I have had three pregnancies that have given me four children in the past six years. I have been nursing for six years straight – minus 3 months this past spring & summer when I weaned my 3 year old twins to give myself a “break” before the new baby came. During my first pregnancy, my breasts were gigantic -FFF or HHH or something ridiculous. My first born only took to one breast, and I was too shy (at the time) to figure out how to fix it. It resulted in my left breast going back down to a B and the right breast stayed at a FFF. I was awfully lopsided.
