There is a lot of speculation surrounding the future birth of baby number two, it is far too early to know which country he/she will be born in. Madeleine and Chris probably have not even decided themselves yet. As for Madeleine using her second pregnancy, as an excuse to get out of going to Carl Philip and Emma's wedding I seriously doubt that she would do that. I think she would want to go regardless of whether she likes Sofia or not. I feel Madeleine would only not attend, if it was because of her pregnancy being so far in the late stage or she had just given birth.
