My son is 25 months old. We started introducing potty when he was 18 months old. We didn't put any pressure on him. We have been giving him a lot of naked time--almost all the time when we are home. He has been accident-free when naked for a month or so, but if he is wearing anything, be it cloth underwear or diaper, he would go in them. It doesn't seem to bother him if his pants are wet. Also, he refuses to sit on the potty and try when we remind him it's about time. Please help!
