Over the Christmas holidays at her German granny’s, our little girl (18 months old as of yesterday) has perfected the art of saying “yes” and “no” with her head.
We have made some educated guesses at the syllables that she’s been uttering in the past two weeks:
“ga-ga” – (rubber) duck – from “quack-quack” (sound ducks make in German)
“ca-ca” – poo/BM (the French term)
“co-co” – coucou or kuckuck (French and German respectively when doing hide-and-seek or waving at each other) – but might also mean a host of other things
“ma” – Oma (German for granny) – the missing “o” is akin to “lala” for “ohlàlà” (French)
“mama” and “papa” go without saying, though the former can also mean “mine”, “I want this”, or protest against whatever it is we’re telling her she can’t have.

Tonight after supper she asked for her cheese and said “Kase”. (The correct German term is “Käse” but I won’t be nitpicking at this early stage. ;-))
Unfortunately I have no adult witness for the scene, so I can just hope for a repeat at the next cheese-after-supper occasion.
