Hi and thanks for your question. It is fair to say that the larger and "saggier" the breasts the more that is required to lift and achieve the "ideal" breasts, however, it is not that much more significant. If you choose to have your breasts lifted before falling pregnant then there are a few things you need to accept:1) they may need to be re shaped once you've finished having children as the huge fluctuations in volume when lactating can continue to stretch the breast skin irreversibly. 2) depending on the extent of the lift required, and in particular how much nipple movement is required, there may be increased difficulties with breast feeding. 3) there is a risk the scars may widen/ stretch if the breasts enlarge significantly. Lots of my patients still opt for a breast lift before having children and are very happy with their choice. Your Specialist Plastic Surgeon will help guide you through this process, you'll be in good hands.
