too much lisp
I was thinking about what we should encourage Child to call the grandparents-to-be, and it suddenly occurred to me: if we were to revive the rather old-fashioned words "Grandpapa" and "Grandmama", we could tweak them to disambiguate between maternal and paternal grandparents: you have Grandmama and Grandmapa, and Grandpama and Grandpapa. And, even better, this gives a simple way of referring to people further up the tree: Grandmamapama, etc.
