Gavriel Zev has a word that sort of sounds like "Ghakkie" that started out as being his word for 'kakkie' (poop) but also applies to a variety of other similarly sounding words.
Sometimes he says 'ghakkie' if he wants a cookie, or if he sees a doggie.
This morning he said 'ghakkie' because he wanted some of Jennifer's coffee.
He also tries to say Ghakkie Mouse when he says the Disney cartoon.
So, you've really got to make sure what he is talking about otherwise you might find a smelly surprise on the floor. (I forgot to mention that we've been toilet training him by letting him walk around without a diaper or underpants)
