We only have one child, no family here here in Australia and our parents are getting elderly. About 5 years ago we opted, in a Will, for some close friends in the UK to look after him, but they'd want to take him back there. Now he's settled with a wide range of friends, we're going to have to re-examine our options. It could be friends here, or other relatives in the UK. It's something we're going to have to reconsider, and soon.
