Personally I think that women that use the excuse of saggy bbs have heard horror stories about bf attempts and dont want to risk having difficulties, but they don't want to share this fear because they feel they will b judged, but thats just my opinion, and it's probably wrong but i like to think it. It would be lovely in a generation or 2 time to be able to say to our kids n grandkids that the generations b4 had a disadvantage in that FF was looked upon as the best thing by the general public and BF was not tolerated but in their time both are accepted as a way to feed your baby and that the only reason formula is used is medical intervention for those who can't bf.
When I was at school, my biology teacher made sure he told us that BF does not cause sagginess and I think it is being taught in schools now because of the FF history. I can't believe how many ppl are so passionate about this!
