My daughter is six also and I used to have the same problem. She has always had a night light in her room so her excuse was not that she was scared of the dark but simply that she wanted to be in the bed with me. She is very independent when it comes to everything else and strong minded. I informed her that only babies slept with their parents and that if she wanted to be treated like one, I most certainly had no problem doing that and explained to her how things like her independence would change. She would not get to choose when she wanted to be a "BIG GIRl" and when she did not. It's one or the other sweetheart and I will support you either way. She didn't have to think about it long before she decide she was going to be a "BIG GIRL". Now don't get me wrong she did try a few times after that conversation to sucker me into staying with her till she dosed off however a simply reminder of her decision and mentioning how proud I was of my Big Gril was all it took. Hope this helps!
