Maybe we can also speculate on whether they're going to have boys or girls? I think both of them will have boys. Maybe we can add a poll with these options?
-both of them will have a boy
-both of them will have a girl
-Mabel will have a girl, Laurentien will have a boy
-Laurentien will have a girl, Mabel will have a boy
I guess the names will be quite a surprise, as normal with the DRF. It could as well be that Wilhelmina or Willem will be one of the christening names, but I don't think they will be the first names of the children. I'm still hoping for a Juliana, Julie or something like that (if there are going to be any girls) or a Sophie. I think these names wil have to come from Laurentien & Constantijn, because Mabel & Friso will probably choose something weird. I would have loved the name Ninette for Luana, I think it's way better (though it might be a bit old fashioned).
