genlyn is right. let your kid do it on his own time. i recently started training my daughter, who is only 20 months. she demanded to be trained twice, and so i started. she decided that she was not ready to dive in full-force, so we are taking it slow for now. instead of wearing undies all day, we only do it for half the day. this seems to be helping a great deal with her. it eliminated the tears, and tantrums. hope this helps, and good luck. potty training is something i have dreaded since i was pregnant! keep it upbeat, and possitive. don't let yourself get too worked up over it. no child will go off to college in diapers, as they say. don't bother with rewards. potty training is not about morals. it's about growing up, and doing what the rest of the world does. just put him in undies, and take him in there every 15 minutes. set an egg timer, and tell him when the bell ding's, it's potty time.
