My 2-year-old has redness at the tip of his penis and says it hurts. When lightly touched, he confirms sensitivity. What should I do?

In a situation like this, it is important to consult a doctor for a proper examination. The doctor will be able to determine if the redness and pain are due to an infection, irritation, or a possible issue with the foreskin. In the meantime, you can give some pain relief medication like Tylenol™ and avoid touching the area. It is best to seek professional medical advice in this situation.
