M.S.
Well I will tell you, you are not alone on this one. Many of the little ones now days are taking longer to get "potty-trained". My 3 year old grandaughter still will not tell us, but at the babysitters will go on the potty. However its only becasue the sitter schedules her to sit on the potty. But at home, or with family, she cries the whole time on the potty and wont tell us. We have tried treats in a glass vase in the bathroom (jelly beans etc) for a reward. This worked great for my kids...but she was not interested...but you might find that a great 'trick".
