If you are staging your surgery there are no proven rules about time between operations but I would suggest 3-4 months as a minimum
Breast augmentations are often combined with an abdominoplasty and liposuction. This combination is common aftern childbirth, and therefore coined a "Mommy Makeover." Doing the procedures together saves time and money and allows you to go through just one recovery. If you wish to space out the operations, however, many surgeons prefer to wait several months between surgeries.See the link below for more info. A detailed examination will help delineate the best surgical option. Consultation with a surgeon certified by the American Board of Plastic Surgery would be the next best step.
