Thrush (Oral Candidiasis):
A parent's guide for infants and babies

Thrush may make eating and drinking uncomfortable, and children with thrush may lose water in their body tissues, becoming dehydrated. It is important to make sure your child maintains good nutrition and fluid intake (hydration) while infected with thrush.

See your child's doctor for treatment of thrush with prescription medications.
Thrush requires medication, which your child's doctor will prescribe after a visit for evaluation. If your child has an immune system deficiency, you will need even quicker and more aggressive treatment to keep the yeast out of the bloodstream and prevent it from infecting other parts of the body. Seek immediate medical attention if the white or yellow membranes of thrush are accompanied by fever, chills, vomiting, or overall illness.
