I also know about having serious upheaval in the very early weeks of a being a new mum. I'm sorry you had to go through it. The thing is even if you had known this information, you may well have still weaned - and that would have still been ok, because you would have done what was, at the time, necessary for you and your family. But for some reason you were deemed to fragile and precious to be given the truth - and allowed to make your own mind up. That's not right! You (and me, and everyone else) should be told more, allowed to be educated about these things, and then left to decide on our own. We are, after all, the ones who have to live with and possibly repeatedly justify, our decision to.

I hope you don't mind me using you as my example ()

And it's not just breastfeeding, but many other aspects of our lives. I was fascinated to learn about the new information regarding 'The first nine months" - how a person's live can be irrevocably shaped during pregnancy. It's great to know this stuff. Would it have changed the way i behaved while i was pregnant? Probably. Bring on knowledge and education. Then let us decide for ourselves.
No, I don't mind you using me as an example I guess for me, I tend to see myself as quite an 'educated' person, having done two post-grad courses (one a Masters), so it almost makes me feel 'dumb' not to have known this. I mean, in my sleep deprived state of looking after a newborn and also getting up every two hours (often never at the time of DD) to give my husband medication, I tried to do a bit of research, but I didn't come up with anything like this. I just wish this info was more well known. Like you said, I may have still made the same choice, but at least I would have been able to do that knowing all the facts.
