I'm not the best person to answer. I'm Nana to mine, but am thinking of discreetly changing my own spelling, having just got back from Malta and hearing that their word for grandmother is Nanna with two ns, as in Terribull's post above. All my three are under four, so none of them have written it yet
DGS1 has always called me Nana Maggie, which I love.
Have any of you got all electric cars? Pros and cons please.
