Thrush is an oral mucosal lesion caused by an infection of Candida albicans, commonly seen in infants and young children, especially those with low immunity or those taking steroids and other immunosuppressants. The treatment mainly involves symptomatic and supportive care, which may include topical medication. Diet management is also important; it is advisable to provide rice soup, glucose, and vitamin-rich foods, while avoiding high-sugar, stimulative, and greasy foods to prevent worsening the symptoms and discomfort in children. Lastly, hygiene related to the child’s feeding equipment, including pacifiers, bottles, and spoons, should be maintained by timely sterilization. Breastfeeding mothers should also pay attention to the hygiene of the breasts and nipples to prevent recurrent episodes of thrush. (Please follow the guidance of a professional physician for medication usage and do not self-medicate.)
