I'm Nannie, with an 'ie', and very proud of it! My mum & MiL were both Nannie to my children, which changed to Nan, when my children were older. Both of my GMs were Nannie/Nan to me, and so were both of my great GMs. Strangely enough, I don't get paid to be Nannie, and neither did any of mine! They are/were just those lovely ladies we mostly adore, who show us lots of love, kindness and cuddles, amongst many other things. I don't see what difference a name makes, or why some people have to be so critical/snide about what other GMs are called. Just be happy with whatever your GC calls you, and thank your lucky stars that you have them!
