My b was over 2 before he was willing to sit on the potty. He did not like the 1st one so I had to buy a second potty. Did u let yr b choose the potty?
We borrowed picture books on the subject about kids doing potty training. One is called Arnie the Pig takes a poo poo (drawn by a Taiwanese).
It took many months before he succeeded as he hated the potty at first.
Praise him like a hero each time he suceeds. Then he will be proud to do it next time.
