If I get a breast lift before I have kids, will my breast sag after I have kids?

During pregnancy, the breast increases in size ( volume) in order to produce the milk to feed the newborn. In some cases, the enlargement of the breast could be significant, to the point that can cause excesive  stretching of the breast, and subsequent "sagging" of the breast once the lactation period has passed. Therefore, patients who have undergone breast reduction, may develop sagging breasts if their breast significantly increase in volume/size during pregnancy/lactation. Family history ( sisters, mother) may suggest how the breast of a patient may behave during pregnancy

Thank you for asking. This is a personal decision with differences between a person's goals, lifestyle and physical exam. Breasts will change substantially after pregnancy and a procedure beforehand may need revision later. Discuss the pros and cons with a board certified plastic surgeon. Best woshrs

If you are thinking about having a child in the next year or working on it now, I would suggest that you wait because your post-pregnancy breasts might look different from your current pair. During pregnancy, your breasts will enlarge from hormonal changes and milk production. Afterward, they might return to their original size or get smaller, bigger or droopier. You won’t know the verdict until six months after you have stopped breastfeeding or, if you are not breastfeeding, six months after childbirth.
If parenthood is further in your future and you anxious for a change now, you don’t have to wait. Just understand that you might need a revision after pregnancy.Either way, there's no reason not to have a consultation now to get the information you need to make your decision.Best wishes,Dr. Ted Eisenberg
