Thrush is caused by an infection of the oral mucosa with Candida albicans, so the treatment focuses on addressing this cause. It is advisable to wash the oral cavity with 2% baking soda water, 3-4 times a day, which generally leads to recovery. If the effect is still not satisfactory, nystatin can be added, dissolved in 2% baking soda water for oral application. Of course, thrush infections are very prone to recurrence. The most important factor causing recurrence is hygiene. Therefore, all items such as bottles, cups, and spoons that come into contact with the baby's mouth should be boiled and sterilized after each use. If breastfeeding, the mother's breasts and nipples should be cleaned with 2% baking soda before and after feeding to avoid recurrence. (Medication should be used under the guidance of a doctor.)
