I would just keep the child in pullups and not go to the trouble - make the child's life miserable by going on the potty every 15 minutes (just as soon as they get settled into an activity) and repeat till they pee. After they pee they get to play a full half hour before repeating the process. If child is not able to stay dry for that time they are physically not ready anyways. I train only with pull ups and have only once in 25 years of doing this had a child that went off to JK not trained. Not my job to clean up accidents on the floor unless they are truly accidents - ie once every 6 months cause child is sick.
