If you were able to breastfeed before surgery, there is no reason to assume you will not be able to nurse after a breast lift. The doctor will incorporate your desire to breastfeed into his overall surgical plan by ensuring your incisions are made in the right location, and that the nipple ducts are protected and spared from excess scar tissue. As much of the natural breast mound as possible is kept intact to guarantee lactating at a future date. The only reason to avoid breast lift surgery until after you are finished having children is because breastfeeding can contribute to breast ptosis, so this might counteract or reverse the effects of a previous cosmetic surgical procedure.
