After a week or so, his skin would become less sensitive to chemical irritation and the slower growing fungus would make its own adjustments to the moist environment and increase it’s population to balance the growth of the bacterial colony. The yeast multiplied rapidly in the presence of water and would soon begin inhibiting bacterial growth on its own. Within two weeks, his skin would have the same relative proportions of microflora that any infant had and his skin would become substantially less sensitive to ammonia in self-defense. After that occurred, unless Andrew was kept in a wet diaper for an inordinate time, he would not suffer any deleterious effects of being in wet diapers. Using barrier creams or anti-diaper rash ointments only delayed the inevitable. The ecology of his skin had to readjust to it’s changed conditions. Krystyn knew that Andrew’s mind had to using diapers as well. It was better that he suffer early on when he still had most of his adult faculties and was less fussy, then have an extreme case of diaper rash once he had accepted his role and would begin crying unceasingly at the slightest sense of discomfort.
For those reasons, Krystyn didn’t put any vaseline or baby powder on Andrew’s pubes before she rediapered him. That would come later, first he had to get used to his new station in life and let his body adjust. If he started crying and whimpering in frustration and pain from his diapers early on, so much the better.
