Writer, I had a lot of problems with BFing. In fact, there were pretty bad problems on and off for the first year. It is a common myth that women who breastfeed, especially those who keep it going for any length of time, find it effortless, which is so not the case, so thanks for asking that question.
I didn't feel pressurised at all to BF. In fact, everyone I know, even FFers agree that the pressure comes from people trying to persuade you to switch to formula. The health benefits of it mattered to me too. But my main driving force was that my DS clearly loved, wanted and needed it so much, and it created such a lovely bond between us, and, despite the problems, it was so helpful (sleeping, upsets, illness, etc.) too, that I just thought 'suck it up' to myself, I got through the issues, and he is still Bfing at gone 3.
Now, I don't think anyone else should 'suck it up' if they feel things are too much for them, or that Bfing is the only way to create a strong bond, just that that's what worked for me and DS.
I will say here that I don't think there is much discernible difference between FFed babies and BFed babies when the BFing stopped before 6months or even a year. The longer my son BFs, and I know other mums in RL who BF, or have BFed, their kids past age 2, the more I see benefits and differences. Some of these are behavioural and emotional, as they have access to a powerful, familiar source of comfort that's been continuous throught their entire lives. Humans are meant to BF until they get their adult teeth in, so I think it makes sense that any benefits only start to show when a child has been BF or not for several years.
