For various reasons I do not, and will not be having, children of my own. My sister has two children who are currently very young (under 5). They live locally and I try and have a big part in their lives, seeing them regularly, spending time with them etc.
I love them - obviously not as mother would (although clearly I don't know what this feels like) but "love" best sums up my feelings for them.
The kids are quite keen on me and seem to like having me around. However, I am aware that as they grow older that will probably change and I'll just be this boring spinster aunt who they're forced to see now and again.
I suppose I'm looking for stories from the future - if your kids have an aunt like me and are older - do they still want to see her?
