The person to whom you should address the answer is of course his pediatrician. If the problem is new, also make a list of changes in your son’s life in the months just before.

Any new friends? Any old friends move away? Any new school or grade change?

Keep a potty diary for your son, or better yet, teach him to keep one. Just write the time, #1 or #2, and whether or not he actually made it to toilet (such as "1pm, #1, yes"). Very basic, very simple, but a way to keep track. This may be helpful to his doctor, too.

Often, changes are the biggest cause. It could be a good change, or a negative change. An old friend leaving, problems with family, etc. Other possible causes are infections, such as UTI’s, though these are really more common in girls than boys. I must mention that abuse is also always a possibility, but handle that subject carefully.

Anyway, these are just a few ramblings on the topic; but he really needs a good evaluation to determine the cause.

Cheers
