Dear Jeanne, You posted about an infant hospitilized for mastisis and then told to supplement to reduce hormonal influence to the baby. I had a case of a baby girl who developed mastisis wihtin the first 2 weeks of life. She was treated with antibotics as an out-patient and her mother did not supplement with ABM. The infection took around a week to improve and never had a relapse of infection. I don't know where this phycisian got this idea but it not a valid one. If it helps to relate my case to your mom please do so and maybe educate the doc. Ann Perry RN IBCLC Massachusetts,Ma. USA
