Why is it that when a person asks a question about formula feeding do feeding mothers have to jump in and be so preachy? We all know is best but is it not a mothers right to feed her child how ever she chooses? It is not child abuse to feed a baby formula and it is not neglectful to feed a baby formula. I have done both feeding (first 3 months) and bottle feeding and i tell you my daughter benefited more from formula than -milk.
