A.M.
I personally don't have any knowledge on this subject, however a friend of mine had a breast reduction and had to have her nipples moved and also made to be smaller. She has successfully breastfed for over 9 months. She was having difficulty on one side because of an inverted nipple so she quit using that side. But her son is a BIG boy and is very healthy. She does use formula but she has only been using formula for about 4 months. Hope this helps...
