Well.. my DD trained at 2 yrs, 7 months. (DD is not gifted) I remember it vividly because it was only two weeks bf my grandmother died. I came home with a beany baby, if was the beginning of the craze. Told my daughter should could have it after she was dry for a day, she did it two days later and she was fully trained a few days after that when we traveled to say goodby to my grandmother. It was that fast.

On the other hand my DS was a pain to train. He HAD to train or we couldn't change his daycare situation, they required a child be out of diapers to move them to the preschool. He NEEDED out of the baby/toddler center he was in because of needed intellectual stimulation. The toys/books they had at the infant center were really limited him. The kid could READ, but didn't want out of his diapers. (The kids would hold it till I put a diaper back on because we were going in the car.) It was a motivation issue, not a control issue.
