My daughter started exactly this at around the same time. She is 2 1/2 and has been pooping in the potty since. I didn't do any "tricks" or rewards. And, I didn't spend my money on potty chairs, she climbs up all on her own. She has always been attached to me, following me almost everywhere. She already had some idea of the concept. So, when she started showing signs, I would just sit her on the potty. Time and patience was all it took. Peeing is taking longer, but I'm following her cues. She knew what to do, she just didn't have complete grasp of it. Now, she is doing really well. Unlike my son, if she has a diaper on, she uses it. I have her in panties all day and she does great with only a couple of accidents these last few days. She has always been very proud of herself when she does something great, so it doesn't take much for her. A high-five goes a long way with her. So, no major reward system for her either. Parents praise goes a long way for most kids. They want to see us happy and proud of them.
Take your time and don't push her. Follow her cues and if it doesn't work, so what, she's still young.
