White blood cells are produced in the bone marrow. They are released into the bloodstream and travel wherever they are needed. Low levels of neutrophils occur when the bone marrow cannot replace them as fast as needed. In babies, the most common cause is infection. A very severe infection may cause neutrophils to be used up quickly. It may also prevent the bone marrow from producing more neutrophils. Sometimes, an infant who is not sick will have a low neutrophil count for no obvious reason.
