No, and we've been meaning to sort this out for ages
Thing is, we just can't think of anyone who would be guardians, which is rather sad really..
Our parents all too elderly.
DH's sisters unmarried, no kids and resolutely single/ independent
Other one already has one child (and was our original thought) but is now getting divorced from her husband (alcohol problems). I wouldn't want to burden her with 2 more kids as a single parent.
My brother is gay, no kids, no experience.
Closest friends (another choice) now have adopted two more children (so now have 4 !) and we just can't really think who else. A few years ago we had some friends in mind, but then they moved away, and we've hardly seen them since...
It's a real dilemma
