I went to the site and looked at the prior article about her going to the Nobel awards by herself. It seems that her husband works here and they live in NYC. So, this decision makes sense and implies nothing really about either her health or her feelings for Sweden; which I’m sure are warm and patriotic as would be appropriate for a Princess. And I hope her health is excellent and all goes well for her and her baby.
When does royalty get born outside the country they are potentially ruling? I definitely take it she wants this baby to be a U.S. citizen.
