Feeding Practices Interpretation
While the world has impressively mastered getting newborns to the breast within the first hour, our follow-through is abysmal, as we collectively fumble the fundamental act of feeding our youngest children with the exclusive nourishment they need, then often fail to introduce them to a truly diverse and adequate diet, revealing a global gap between good intentions and sustained nutritional action.
