Dear Jane, This topic has actually been covered on the Lactnet, giving human milk to sick children and adults. There should be no reason formula would be better than human milk. There are a couple people at Children's Hospital in Boston she should seek out for support. Barbara Marino, PhD, RN, nurse researcher at Children's. The other option is to have them contact a IBCLC consultant there in the hospital. Good luck, please feel free to contact me directly. Ann Perry RN IBCLC
