no. i would not recommended it since formula would be a safer alternative for the baby and reduce the risk of transferring a bacterial pathogen from the mother. there are ways to keep up the supply of breast milk (and discarding it) until the meningitis is cured and the blood/breast milk are safe again. if the mother has bacterial meningitis she is usually too ill to be caring for a baby. she is most likely going to be on intravenous antibiotics some of which are excreted in the breast milk and not safe for the baby.
can you still breast feed with bacterial menengitis? while being treated?
