K.,
My oldest daughter just turned 3 in April and I started the potty when she was about 20 months, she wasn't real interested in going potty on it to much, but just to get her interested in wanting to. At about 27 months she started pooping on it, but wouldn't pee in it. So I thought about bribing her, that didn't work so well either. It made her revert to not even pooping on it, so I gave that up and didn't push the potty anymore. She was maybe 2 1/2, we had went to the circus, when we got home she said she had to go potty, took off her pull-up and handed it to me and said no more pull ups, I'm a big girl. And from that moment on, she was potty trained. Had a few accidents, but that is expected. So, I'd say bring potty chair out, let her get used to being around it, even if she just wants to sit on it. Just keep telling her what it is for. You could put her in pull ups and tell her that's the next step to being a big girl. But everyone says not to go back and forth with diapers and pull ups, they say it can confuse them or something like that. Hope I helped a little, and I don't think she's to young, go for it.
