Hi P. ~
I'm not sure if I will be much help but I strongly believe that, though your child may be very capable of using the potty, I don't believe that you can push a child to use the potty. I think that as long as your introducing the potty to her and she sees your using the potty, she will eventually be interested in it. But the key part is that, she will be ready when "she's" ready! I would say to keep asking her, put don't push her to the point where she rebels.
Here's one way I tried with my kids ~
I introduced the potty to them, showed them over and over how my "pee" comes out and how I get to flush the potty when I'm done, PLUS ~ and here's the magic trick, I think ~ I get a treat for using the potty!!! ;)
I don't give my kids much candy, so when I get candy for using the potty, it's a huge deal for them, therefore, when they are ready to get that candy ~ they'll be ready to use the potty! And once they do ~ make a big deal about it ~ give them their treat and keep reminding them to see if they have to go potty! And once they get it 100% ~ you can eventually take the candy out!
My daughter potty trained herself by the age of 2 1/2 and my son was 3 months shy of his 3rd. birthday.
I hope this helps or at least gives you an idea! Of course ~ everyone has their opinion and I hope this helps a little bit!
Good Luck and Best wishes!!! ;)
Sincerely, A. ;)
