Thrush is inherently prone to recurrence, and the difficulty in eradication is primarily due to poor hygiene, so figuring out how to effectively treat it is crucial. Firstly, active treatment should be implemented. The mouth should be rinsed with 2% baking soda solution at least four times a day. In severe cases, an antifungal agent can be added to the 2% baking soda solution for mouth rinsing. This is the primary step. Secondly, proper hygiene must be maintained. In principle, all items that come into contact with the baby's mouth, including pacifiers and bottles, need to be disinfected promptly. Of course, if breastfeeding, the cleanliness of the nipples and breasts is also very important.
