Breast implants do not interfere with breast feeding as the implants are placed behind the breast tissue and milk ducts. Therefore lactation (breast feeding) can proceed without any problems. Of course care should be taken to maintain the shape achieved by the cosmetic surgery. If pregnancy should occur particular care should be taken in supporting the breasts in order to maintain the best possible shape subsequently. This is achieved by wearing a supportive bra day and night during pregnancy and also whilst breast feeding to provide constant support. If you can limit breast feeding to three months or less this will also reduce the stretching of your breasts and therefore preserve your shape.
