yenna na yenna?

MissPot has been so busy with her mind whirring at top speed that it is sometimes hard to get her attention. Offlate V and I have said something to her and caught her just repeating yenna? 4-5 times before she gets what we are saying. Both of us have asked her "yenna na yenna kanamma (what do you mean what again and again)? - listen to what I am saying". In the last 2 days everytime she says something if I ask yenna? She says "yenna na yenna - oil means oil" - choooooo chweeeeeeet - i just have to hug her at that time.. everytime!
