The problem, OP, is that there is literally no way to convince you.
For me, I believed all the hype. I read up on all the breastfeeding stuff, I did classes before birth, I had a lactation consultant on call. I had nowhere near enough supply to nourish my baby. I just didn't. No matter what I tried, what advice I followed, what I did or didn't do. I was devastated. And while my real life lactation consultant was actually non-judgemental and helpful, every where I turned online made me feel like an utter failure. The constant advice to breastfeed more and more and more simply didn't work as my baby absolutely wouldn't latch or relatch once he sensed that there was no milk there. Following the breastfeeding advice online - which insisted on sitting under the baby feeding (or attempting to feed) endlessly for hours did nothing to enhance my supply and landed me in hospital, as close to death as I have ever been in my entire life. Nobody warned me of the hugely elevated risk of blood clots in the weeks after birth. Pulmonary embolism is still one of the leading causes of maternal death in the UK and I put myself at risk of that because of breastfeeding. So every time I see a post on here, cheerleading for a 'baby moon' and telling a post-partum woman that her breastfeeding problems will be solved if she just "takes to the bed with the baby / doesn't move off the sofa and have her partner wait on her hand and foot because you shouldn't be lifting a finger and your only job is to breastfeed, feed, feed, feed", sure as hell you'll see me chip in with my experiences and warn women that attempting to follow that advice nearly killed me - and I am not saying that metaphorically, I was in real danger of death, rushed to hospital, bumped to the top of a 17-hour queue in A&E, seen immediately and admitted immediately with an enormous team dedicated to ensuring I didn't die and of course without my baby because the type of specialist care I needed isn't available on the maternity ward, only on the intensive medical ward - and no, I am not getting paid a penny by a formula company.
I also feel and empathise deeply with story after story of women who felt the same searing grief, the same enormous sense of failure, at not being able to exclusively breastfeed my child. I had fallen fully for the magical benefits of Breastfeeding narrative and was terrified of giving my baby less than the best. It was a horrid, lonely, agonisingly painful time and it nearly tipped me into depression.
So no, when I see women recount similar experiences, I don't see formula company shills. I see women whose life experience matched my own and I can empathise with them.
I also see no reason why people insist on massively exaggerating the benefits of breastmilk. For my babies, it wouldn't matter if breast milk would give them super powers. The simple fact was I didn't have enough of it. The most basic food-related need any of us have is to get sufficient calories. Adequate accessible quantities of breastmilk may well be marginally better than adequate quantities of formula but for my babies, the first of those options was not available. I did not have enough milk to sustain my infant. I combined-fed for six months but with the benefit of hindsight, I now wonder why I pushed myself so hard to do that. The scientifically proven benefits of breastfeeding (or any other "perfect" diet) are marginal and not hugely convincing.
So no, not a formula company shill, just someone who has had the scales fall from my pro-BF eyes.
