Four-month-old baby has white tongue and red tip of the tongue, always sticking out the tongue, what's the reason?

Patient's question:

No

Doctor's answer:

Hello, the child has white tongue coating with red tip of the tongue, and there is a symptom of protruding tongue, which should be caused by mild internal heat. I suggest giving the child more water to promote the metabolism of heat in the body through urine!
I hope my answer is helpful to you!
