You are correct in trying to loose your pregnancy weight before scheduling your breast reduction because in eliminating as much of the hormonal variability of the postpartum, reducing the fatty component of the breast and getting yourself psychologically fit, you'll truly be ready.
In all discussions with breast reduction patients, I always discuss that there are essentially three phases during which the breast volume may recur. a) Virginal hypertrophy occurs in young women who develop early. b) Postpartum hyperplasia is evident after pregnancy and lactation. c) Involutional hyperplasia is best understood as the extra volume which appears around menopause. So it is possible for a big breasted woman who has a reduction mammoplasty to "grow again", if she has additional pregnancies and as she goes through menopause.
Hope this helps you. Good luck.
