This is about as far from the truth as saying men don't like breasts. In underdeveloped countries unsanitized water mixed with formula can kill the infants that drink it. The only financial gain in breast-feeding is the money the parents save 'NOT' buying formula. Human milk is a living substance, varying from mother to mother to fit her child. It contains every viral antibody the mother has ever been in contact with.
Human milk contains all the vitamins, minerals, iron, fats, sugars, proteins, enzymes and water.
Not one more drink has to pass babies lips, even on a scorching hot day. I'd better get off my soapbox. It's as if the mother and child intuitively know together what the baby needs. A mother can even feed triplets, in one breast-feedingsitting. As you can begin to see and appreciate, anything to do with the breasts shouldn't be rushed or underestimated.
