Hi all, I'm pretty new here but after a bit of lurking there seems to be some great advice.
We are inviting a friend/colleague of mine to the wedding along with her two teenage daughters that I know well. I'm also expecting that she will bring her live-in boyfriend despite the fact that they are on and off practically every week. My question is whether I should invite his two daughters? They are very young and I hardly know them, but I don't want to offend them by only inviting her two children. What's the proper etiquette in this situation? I guess in the long run it doesn't really matter but with our venue size a 6 person invite is no small potatoes!
