Perhaps she'll have Victoria somewhere in her name since the Te Deum coincides with Victoria name day
I know not everyone thinks that with the lack of defense against the unwarranted bad press on Madde, that Victoria deserves to have a niece named after her but I could easily see Madde being the bigger person and using it anyway as a show of loyalty to the future Queen.
Unless it's against tradition to name someone after a living person in Sweden?
No it's not against tradition at all.
In fact, in my family the "family name" is Kristina. Almost every female of every generation is baptized Kristina.
