Alyosha, I actually did know of that opinion article (it's in the section marked 'opinion' which is a clue :) ) in JAMA, Alyosha, but you were referring to research, and I was confident enough to say the research evidence does not exist....which it does not.
That article describes 'unintended' effects of the BFI - of course babies are at risk of serious harm, even death, if they are skin to skin immediately after birth or in the postnatal period (per BFI ) which indeed encourages skin to skin for all babies) with exhausted mothers with no one overseeing safety, or even explaining to the mother how to hold her baby safely. That's 'unintended' effects of rubbish postnatal care. Sudden Unexpected PostNatal Collapse is a known phenomenon and it can happen under any circumstances....oh, just read the article itself jamanetwork.com/journals/jamapediatrics/article-abstract/2546142 and not the Slate report of it.
Baby Friendly USA - because the opinion article was 'about' the USA - responded "The recent article published in JAMA‐Pediatrics titled Unintended Consequences of Current Breastfeeding Initiatives [9]is filled with comments not supported by research. It has triggered a firestorm of on‐line articles with sensational headlines that are
geared towards frightening practitioners and families away from the Baby‐Friendly Hospital Initiative.' This short, evidence-based rebuttal is online.
"If BFI did not exist, the babies would have lived." Of course not. Do you think BFI invented skin to skin? Or avoiding unnecessary supplementation with formula? All the BFI did was take good practice, which had been shown already to be beneficial in research over years and years, and combine it into a programme which was coherent, and practicable.
"There is also some new research that shows more severe long term effects from newborn dehydration: online.liebertpub.com/doi/abs/10.1089/bfm.2016.0054?journalCode=bfm"
I think your point is that I am minimising neonatal hypernatraemic dehydration? Not at all. It is not a good thing, clearly :) But the Iranian babies in 'your' citation (we have no info on their bf status or any maternity unit practice - it's unlikely to be BFI, anyway) appear to be severely affected early on - I can't compare figures with the Oddie (British) babies as the measurements of sodium levels were different, but the Iranian babies had brain swelling, kidney stones and haemmorhage, You'd expect later consequences with that .
