Liron and I were giving D lunch today and suddenly he was talking. I asked him if I could have a piece of his toast and he said "Lo Rotze" (I don't want to) then I asked if he liked his bread and he said "Ken" (yes). Liron and I were staring at each other because we were both hearing all this. Then I asked if it was correct that he liked toast with butter and he said "Nachon" (correct). I asked if he wanted this piece or that piece and he pointed at the one he wanted and said "Ze" (this).
