Is it naked time?

I'm changing Courtney out of her Sunday clothes into play clothes. Once her dress if off she runs away. I call to her saying come back here so I can get you dressed. She yells at me, "need naked time!!!" Even as I catch her and am struggling to get her dressed she's repeating herself, "need naked time!!"

I do have to admit, I think it's grandma's fault (tee hee). While at grandma's recently she noticed a problem with the shirt the girls were wearing. So she took Courtney's shirt off to mend it. When she tried to put it back on; Courtney said no so she let her run around with no shirt. Now most times when Courtney wants to be naked and I don't let her she tells me, "want grandma"
