I posted before about a friend of mine who I am pretty sure is assuming her kid is invited to the wedding and decided to just wait for save the dates to go out and for her to hopefully figure it out. We are sending them now, but we realized we also have another friend who will have a 1-2 month old baby (I am not sure on the exact due date), and we are going to let this friend know that they can bring the baby if they need/want to because it will be so young. Now when the first friends asks me about her kid (I am almost positive she will), I was just going to say we can only invite family kids, but now I feel like I can't really say that because she will be offended if the other couple do bring their baby. But I also feel like if I explain the exception that will leave room for her to argue for another exception. How would you handle this?
