Because your mother has been exposed to antibiotics and because she did have some response to the antifungal medication (Diflucan) then a fungal infection may be her problem. However, both the mom and baby dyad need to be treated. A topical antifungal cream applied to the mother's nipple may be helpful. Treatment would need to last several weeks. If the baby needs a prescription antifungal product the pediatrician should be able to prescribe it. Julie Cold Kissack, Pharm.D.
