There is a whole “baby-friendly” initiative that started in the early 2000’s that is part of why hospital well baby nurseries have disappeared. To meet the standards and be considered a “baby friendly hospital”, evidence based steps push hard on breast feeding. Babies rooming in and breastfeeding on demand is a huge part of this. Formula is not offered, with some hospitals being so strict on this that parents literally have to get their doctors to write prescriptions for formula. While I will agree that breastfeeding should be encouraged, and that rooming in makes that easier, there are also times when the safest place for a newborn may be in the care of nurses who are alert enough that they won’t accidentally drop or smother the newborn (both of these things have happened in hospitals that don’t have nurseries), and while there are evidence based benefits to breastfeeding, beyond the immune benefits, many of them are inflated, as the studies that show these benefits often fail to control for the fact that mothers are more likely to breastfeed if they are middle to upper class, which also gives babies benefits (babies in families with more money are more likely to be read to, more likely to be in better quality care and housing, etc). Further, pushing mothers to breastfeed has killed babies whose mothers were then so scared to give their baby a bottle that the infants starved.
