Need of help ASAP!!!! My daughter can't stomach formula so she is strictly breastmilk but it seems my breastmilk is dying down and barely producing anymore and she is only a little over a week old. Is there anyway I can get my milk supply to get up? Is there anywhere I can get breastmilk til I can supply enough for her again? I live in Riverdale, GA so if anyone is near me and know someone who donates or sell please let me know.
