DS is the same, does pretty well when I remind him, but no poop in the potty. I emailed the preschool director, I explained the state of potty-training, and asked what to do. She replied back today, said they would allow him to start on the 4th, his teacher would give him reminders and work with him, and hopefully seeing all the potty-trained classmates would spur him to complete it! (I'm so relieved!)
