babymutha I could have written your post almost word-for-word (except that I carried on combo feeding but didn't get close to 2 years - well done you!).
DH and I were just looking at DD's newborn pictures yesterday, and after all the loveliness of reliving the first few days, I started crying as we got to day five, day six, and the pictures showed an infant with increasingly dry lips, yellowed skin and eyes, and the (now) unmistakeable look of illness and hunger. I remember that after the emergency hospital admission, the IV fluids, the introduction of the dreaded formula, and the overwhelming relief and gratitude I felt at bringing home a healthy baby who had survived her mother's serious lapse in judgement, I did beat myself up in an awful way about the FACT that I couldn't produce enough milk for my baby.
I've never been so vulnerable in my life - feeling that I'd failed in the first task of the most important role I'd ever have, feeling I'd already failed this perfect, precious child that I had been blessed with. At that time, reading a list like the one linked in the OP, or reading posts like Leonie's, would without exaggeration have been reasons for me to lie awake crying and hating myself while my no-longer-hungry little girl slept blissfully unaware beside me.
I will always carry guilt about my daughter's first weeks of life, but with perspective I know what that guilt is really about: it's about the fact that I allowed my belief in what I thought to be true about infant feeding (that nobody really has supply issues, that breast is always best, that to give her formula would be to fail her) to cloud my own judgement, my own instinct, and my own responsibility to do what was best for my daughter. That is, to not sacrifice her health on the high altar of ebf.
Gaelicsheep, you are absolutely right to split hairs about the semantics. Even after we started supplementing with formula, I always fed my daughter while skin-to-skin, and tried to make the whole feeding experience as bonding and nurturing and lovely as it could possibly be. That would have been very very hard to do if I had stayed in the mindset that by feeding my baby formula I was not actually nourishing her but in fact was actively harming her.
It's important that people understand that breastfeeding is the norm, so I agree that information should be framed in terms of risk rather than benefit. But there is a world of difference between saying that yes, there are risks if you don't exclusively breastfeed (here, if "don't" means "can't" for you, you might find some way to forgive yourself for your body's failing), and saying that the formula itself is dangerous.
Particularly when we know that some women have no other option but to use formula, it is unspeakably cruel to use language that, for some, is likely turn every single feeding session - which should be an opportunity for bonding, sweetness, and lifelong memories - into an exercise in guilt, fear, and self-recrimination. Because those memories last a lifetime, too.
