It is pure and unlimited. There is nothing to buy, carry, heat or measure. It is economical. You can spend money on your foods not formula, bottles, etc. Breast-feeding is ecological.
Breast milk is a valuable, unlimited natural resource.
No special diet is needed for the mother to produce the perfect food for her baby. There is no negative effect to the environment, nothing to dispose of, i.e., no bottles, nipples, cans, etc. Breast milk is easy to digest, never constipating. Babies diapers and spit up don t smell as bad as formula fed babies. Most breast-fed babies are less fussy, colicky than a formula fed baby.
