Because its not just woman X, who made that decision and is happy with it, who is reading the discussion. Its pregnant women all around that world who still may be unfortunately under the mentality we have where formula is percieved as equal to, or even superior to, breast milk. And to be honest, if I briefly piss off woman X, but it means that next time she is pregnant she does a bit more reading and gives breastfeeding a go, then its been worth it. And that does happen, not just with breastfeeding, but all sorts of parenting decisions; you decide that you will do Y with your DC1. You do it. You see a thread / a blog / an article / over hear a discussion when pregnant with DC2 and you reconsider.
We're obviously not going to agree on this Moomins, and obviously that's fine. And obviously there are some people who will not breastfeed at all. Do I think that's unfair on the baby? Yes I do, because as far as I am concerned being a mother is about doing absolutely what is best for your baby, at times despite the impact on you. Now maybe that is because of my own childhood, and things I am hoping to change for my own child. Or maybe its because I am fully educated and aware of the risks of artificially feeding, and they frighten me. So I think everyone should give breastfeeding a go, because if the baby had a voice you can guess what they would ask for :)
That said, I have some lovely friends who have bottle fed right them the off. The fact I disagree with their choice, and would do my absolute to help them the next time around (9/10 of them wish they had breastfed), does not mean I think they are bad people, or bad mothers. I still respect them, love them, and love their children. The ones who had issues and switched to bottles I have even more respect for, and feel disappointed for, because they tried and tried, and were failed by the system.
