I think it is really sad, and quite horrifying that in some cases, it is the partners that are having the issues and so putting pressure on the mums to not BF.
I was the only one amongst my friends who ever BF when I had DD1 (I was 21 then). For me, it was an instinctive and natural thing to do.....I nurtured her while she was in my womb, and so I would continue to do so once I had given birth. I BF all five of my children for the same reason.
My friends however........3 found it repulsive, and told me so......two I have not seen since, their loss not mine......I have better friends since.
one did stay friends, she told me that she only found it repulsive to her, for her own reasons, and wished she could change as she never found watching me (or others) breastfeeding repulsive. I think her attitude was partly a family thing.....she never had the encouragement IMHO.
Another of my friends back then WANTED to BF, but was told in no uncertain terms by her DH that they were HIS breasts, and not for the baby.....utter tosser , and thankfully, she eventually saw him for what he was and they divorced. Sad for the children (she had two by then), but then again, they were at least spared his vitriol against women. As the children were girls, I felt it a very good thing that my friend managed to get away.
I have to say, I do wish that when I was having DD1, I had something like MN......I could have directed my friends here and they could have learnt a lot about how wonderful BF can be, if it works, and if not, get the support so they don;t beat themselves up about it and forever regret.
