Thrush is a yeast infection that causes white patches in the mouth and on
the tongue. Thrush is most common in babies and older adults, but it can occur
at any age.
In babies, it is easy to mistake thrush for milk or formula. It looks like
cottage cheese or milk curds. Don't try to wipe away these patches, because you
can make them red and sore. Some babies with thrush can be cranky and do not
want to eat. Read more
