I am convinced that the three Wales children are getting the best upbringing ever. They are very lucky.
And their special add-on is planned exposure to public occasions such as this one. I always like to watch how they handle the hand shaking moments.

However I must add that I am now over Catherine's loose long hair. Perhaps it is my own upbringing way back, but we usually controlled it in public with ribbons or plaits, as children of course.
