Interpreter

I have always been very good at interpreting what Cade is saying, or I should actually say Cade is just very good at communicating and using his words. However lately he has been saying 1 thing over and over and over and over and I can not for the life of me figure out what he is saying. Is sounds something like this "Mika, mika, ma". I think today alone he said it about 30 times! I have tried saying different things that sound like what he is trying to say such as "mickey, mickey mouse" or "milk, milk mama" but nothing is correct. When I repeat "mika, mika, ma" back to him, exactly as he is saying it to me he always says "YA" right back, like "ya mom that's what I'm saying!" Maybe he is just babbling and I need to give up trying to interpret, but it is so frustrating especially when I have always been able to understand his language.
He is such a crazy silly kid!!
