any one of these chemicals ON THEIR OWN are not in good standing with the human body.. would you give orange juice to a car instead of gasoline???? God gave each woman the ability to feed its own child with exactly what they need to grow and flourish... docs tell them their not growing fast enough.. they grow as they are supposed to. my grand daughters nursing was vorasious. never saw such an aggressive feeder. she was one ounce under what they wanted.. like if she hadnt pooped she would have been okay?? it devastated my daughter.. btw i was a lactation instructor and teacher with good success but my comments didnt count. i was not the doctor...that one hurt me big time but i got over it..
