Diagnosing Breastfeeding Difficulties: Where Do We Stand?
Maternal &Child Nutrition, Volume 22, Issue 1, March 2026.ABSTRACT Despite lactation being a natural occurrence in mammals, many structural barriers and individual factors can impact the ability of a woman to breastfeed her newborn. At the individual level, evidence has widely documented several risk factors and societal barriers for impaired lactation, many of which have been steeply increasing in human ...
