Why would a daycare provider have little incentive to stick to the regimen? In my experience, daycare providers are usually the ones to push parents on potty training. Changing diapers means 1 staff is caring for 1 child. Once a child can go to the bathroom on their own, they have more time to spend with the other children. Additionally they have less waste, less need for storage of diapers and wipes.
I really don't know. My comment is just based on the experiences of friends and family. Parents too busy at home, and little or no support at day care. As mentioned in some sibling comments, today's "super diapers" might not help, as they might be too absorbent.
