Not me kid

I have a Not Me kid. What I mean by that is that every time I say something, she says "Not me". It does not matter what I say she says " Not Me" , sometimes she proceeds to say "Not Q" , "Not L", "Not mom", and "Not dad".
This was all very cute the first few times she said this, but now it has been months and it is getting crazy annoying. I love her but I hope that this stage ends soon!
