thank you for your quick response. you mentioned reading articles. could you give me specific info on where i can get these articles and possibly the names? providing this info to our neonatologists is the only chance i have to try and change how we continue to mix mbm with formula. dr. newman, do you have any input on this subject? that is, the concern of the affect of mixing formula and mbm, 1:1 to give enough volume, either for increased calories or not enough breast milk. does dr.lucas have anything written on this?. thanks again, charleen in syr.
