Thank you for the question. Waiting 3 to 6 months after you have completed breast-feeding, to proceed with elective breast surgery will allow for your breasts to reach a "steady-state" (which will allow for proper planning of the operation). Also, having breast surgery while you are still lactating will expose you to problems such as fluid accumulation (which may require further treatment such as drainage procedures), secondary infections, and/or (potentially) an increased risk of encapxsulation of breast implants. My best advice: select your plastic surgeon carefully. Make sure that he/she is a board certified plastic surgeon can demonstrate lots of experience safely achieving the types of outcomes you would be pleased with. Then, wait until you reached your long-term stable weight and are several months out of lactation prior to proceeding.Best wishes.
You should wait 3-6 months after you stop breastfeeding before considering breast augmentation. This allows time for the breasts to return to a stable state. It will allow you and surgeon to better determine appropriate implant size and style and also see if a lift is recommended.
