I just thought that when the succession laws were changed in Sweden it was not just for equality reasons but also a fear that yet another generation would have to go on having children in order to provide the throne with an heir.

Had they not changed the line of succession the king still would have had three heirs and possibly a fourth on the way.
Still i believe Sweden made the right choice, im not sure if Carl Philip would have been allowed to marry Sofia had he been the crown prince and i think Victoria is better suited to the role of heiress than he would have been to the role of heir. Or at least she seems to be. I believe Carl Philip and Sofia prefer their current role that leaves more freedom for themselves and their children.
