My child is three years old, only knows how to say "daddy" and "mummy," and always catches colds.

Patient's question:

In May 2012, I contracted a cold, fever, and it developed into pneumonia. I sought medical attention at the local county hospital.

Doctor's answer:

Baby, this is a condition caused by low physical resistance. You can use some Transfer Factor Oral Liquid. It can enhance the body's resistance. It can reduce the recurrence of diseases.
