What causes thrush?
An overgrowth of the Candida fungus in the mouth or throat is what causes thrush.
Thrush in infants is relatively common and is only a concern if it causes poor feeding or is associated with weight loss or other symptoms of systemic illness. Consult a pediatrician if thrush in an infant lasts more than a couple of weeks.
