Translation Anyone?

I remember when Addie was about Edith's age she said one word all the time. The problem was no one could figure out what she was trying to say. I think it was something like "ziggy." Well we now have Edith's mystery word. It is something like "notchoo." Kind of a cross between "not you" and "nacho." Anyone have any ideas what this means? Edith is quite patient and says it over and over to us while we guess what she is trying to tell us.
