Christine, my first child, was using the potty at 7 months old, but only if I set her on it. Obviously she couldn't ask to go, but when set on it, she went. Then I got pregnant, positive result when she was 8 months, so I gave up on it as I was too tired. She had just turned 2 years when she told me that she didn't want to use nappies any more, just pants, and she never had any accidents. My next 2 children were 2yrs and 8 months, and 2 yrs 9 months before they were out of nappies, but I didn't mind.
If you think she is ready now, give her a go at wearing pants, she may surprise you.
I think first children are quicker at these things anyway.
