Thrush is a yeast infection in your child's mouth.

The main symptom of thrush is a white, cheese-like coating inside your child's mouth.

A medicine, prescribed by your health care provider, should clear the symptoms in 7 to 14 days.

If your baby bottle feeds or uses a pacifier, boil the items for 10 minutes each day.
