15 month old baby removed?

From what I have read, the child was not removed because the mother breastfed, the child was removed because the mother refused after several attempts to nourish her child properly. The article states that on weekends the mother solely breastfeeds, this in not sufficient nourishment for a child of 15 months. This mother is neglecting her child by solely breastfeeding. What exactly is the problem with authorities stepping in to ensure that baby Alma is properly fed? The mother WAS neglecting her child by not feeding her properly on weekends.
