My 20-month-old son has a red tip of the penis. Nothing has changed in his habits and his buttocks are not irritated. What should I do?

In a situation like this, it may be helpful to apply zinc oxide cream to the tip of the penis at each diaper change and try to minimize the amount of time your child wears a diaper during the day. The redness is likely due to friction from the diaper and the moisture it contains. This simple remedy should help alleviate the issue.
