This makes sense to me in every way - the Swedish royal house were on the way to grow exponentially.

It puzzles me though that this decision weren’t made when Madeleine had her first child. To let all the grandchildren be born as royal highnesses, receiving a dukedom etc. - and then change it after a few years.

However, I’m glad it was done now instead of leaving the “cleaning-up-process” to a future Queen Victoria - so much easier for the King when it his children and grandchildren that is the subject of the decision.
