Hi K.. I am C. and have a 5 year old son. I actually waited until about 3 1/2 even though my son was potty trained by the time he was 2 1/2. Then when he was giving me problems about it, I threw a handful of Cheerios into the toilet and made a game out of it for him. He tried really hard to hit the Cheerios and I rarely had a wet floor. Good luck!!!
