Our twins' favourite people in the entire world are my wife's parents - who they know as Granny and Grandpa.

But being under two they've not quite mastered these two words yet. Granny is apparently "Momo" and Grandpa is known as "Bumpa".

That was until we visited over the New Year. Now it seems both twins seem to have evolved "Bumpa" into something that sounds almost like "Bumhole".

It's actually so clear that at one point my surprised brother-in-law said to the twins "Don't call me dad a bumhole!"

Kids eh?
