Should I consult a doctor if my 18-month-old daughter seems to have thrush on her tongue? She has white patches at the back of her tongue.

If your baby has never had a prescription for thrush before, it is important to see a doctor for a diagnosis. In this case, it is recommended to wait until your scheduled appointment on Wednesday to discuss the issue with the doctor. If it had been previously diagnosed and treated, a doctor could potentially prescribe medication without needing to see the baby in person. However, for a first episode, it is best to have it properly evaluated by a healthcare professional.
