Hi K.,
Don't be embarassed. I did the same thing because I hate whining and my daughter told me that nothing was wrong. I would ask her constantly and she'd say nope. She also says "what" all the time but it seems like selective hearing. She has tubes, or did. I took my daughter to the ENT to find out that she has fluid in her ears and her tubes fell out (after a little over a year). She is getting another set of tubes this week. I asked the doctor if she was kidding when she said "what" and turn the radio louder. The doctor said probably not. So, with that said, I would suggest taking your daughter to the doctor. I find my daughter whines more when there is something wrong. Oh yah, a cure for that is to ignor the whining or say "hmmm, I'm hearing you say I want to go to bed through that whining" and that stops it also.
Good luck,
S.
