Implants will not usually affect breastfeeding. If your breasts developed normally during puberty, you should have no trouble with breastfeeding. The size of the original breast tissue is not important for breastfeeding, it is the shape and the way the breasts developed during puberty. Before you had implants, if your breasts had a wide space between them, were significantly different in size and shape, had only a full areola and nipple and no other breast tissue, had a cone shape or the nipples pointed to the sides, this may mean that they did not develop completely and therefore may have trouble making milk.
