DD kinda randomly used the potty chair on monday and peed a little in it to our surprise. And that night she went two more times and several times since then.
To encourage her after the first time she peed I gave her a peice of candy (actually a chocolate chip) which is a real treat in our house! So now she's learned that she can pee, flush, get her candy. Then pee, flush and get more candy. So she can stop/start her pee in order to maximize her candy consumption! It totally cracks me up.
As much as I never wanted to use food as a reward (one of those never say never things) stickers and toys weren't as exciting to her as the candy or cookies were. *sigh* I just think it's kinda funny how she's learned to manipulate at such a young age already!!
