Since my son is a professional sportsman he has to pass medical examinations regularly twice a year. If he passes it he gets medical permission to take part in training sessions and competitions.
I remembered how we came to that medical examination first time. There were many little kids and their parents and most of them came the first time too. We spent many hours passing through all medical specialists.
Nowadays, my son passes this examination himself just in a couple of hours because he has known everything about it. What specialist is better to visit first, which documents to prepare and when.
I guess, a such event is very useful, because a regular medical examination lets monitor health and find any deviations. And besides, it is good training of the child's independence.
