In our family, like many others I'm sure, we have little made up words for everyday things to make it easier for the toddlers as they learn to speak and for the adults to understand.
For example,
boo-boo = a hurt or a scare, be-bette = an insect, bankie = blankie
The one that really stands out though was 'na-na' which meant food. For a 6 year old, the most logical conclusion as to why we called my step-grandmother 'Nana' was because she was always eating. :-X
