Assuming that, as reported, they will be at Frogmore Cottage when Meghan goes into labor or it's a planned C-section for some reason, they might be planning to do the Lindo Wing if all is going as expected, but Frimley is close by if something goes wrong.
Just pointing out with all this talk of a planned c-section and posters asking where that information came from....I think the poster was simply saying that if she needed a planned c-section for any reason then the Lindo Wing was probable. Please correct me if I'm wrong, as I'm sure many will, but I really don't think anyone was implying that a c-section is planned or that that information is floating around out there somewhere. Just pointing out the possibility and the difference it could make in the hospital they choose.
