To toilet train your child, have him or her sit on the toilet (taking breaks every half hour) for as long as you CAN. Dr. Kroeger and her team literally spend all day in the bathroom, from the time the child wakes up until he goes to bed. Drinks, food, and playtime can all take place in the bathroom.
Sooner or later, during the course of the day, your child will urinate into the toilet. When he or she does do the deed, celebrate! Give your special motivators, toot horns, whatever it takes to show that you're proud. Take a break, and then go right back to the toilet.
