I hated breastfeeding- I hated it from day one. I think I struggled for about 3 months. It never got any better, hurt and made me feel physically sick.
I could not care less whether women like painting disapproves of my unfeminist choice to stop. My own mental and phyisical health was more important. Given my son is 28 and the last time he had to see any medical professional for anything was to get his MMR I am unconvinced I failed him by giving up.
I don't disapprove of your decision, nor do I think it was unfeminist or that you failed your child. Me disapproving of you FF would be as ridiculous as you telling me I'd failed my children by bringing them up in a city, where pollution is a risk to their health. We make choices about our parenting for a multitude of reasons, and taking the route of optimum health isn't always achievable - or even desirable - give the factors we're dealing with in our own lives.
I am sorry to hear you had such a shit time BFing though. As you started it, and put up with it being so bad for 3 months, imagine you wanted BF? I'm sorry it wasn't easier for you, it sounds like a horrendous experience and I don't blame you one bit!
But, I can't help wondering if you might have had a different experience given better support. (e.g. perhaps your baby had undiagnosed tongue tie - it shouldn't hurt for 3 months - or perhaps there was some other reason). There's pretty good evidence to show that what stops women BFing is lack of decent support, not lack of the intention to.
It's why the "breast is best " message is a crude tool, and one which people are now starting to move away from, thankfully. Repeatedly bashing mothers over the head with a message that says, basically "breast is best, do this for your child - else you're failing them!!" isn't that effective. It's aimed at getting mothers BFing at the start - but without putting in the necessary resources to support BFing longer term. It isn't a great recipe for success IMO and it's not surprising it makes mothers feel resentful. There's only so many times a campaign can tell us that something is good for our child - if circumstances mean we're unable to do it, or it's difficult to, telling us again and again what we already know, isn't actually very helpful and possibly even counter productive.
