I am currently taking a long road to becoming a neuroscientist, and I would like to take a look at why we like diapers from a neurological stand point. Each brain has its own unique heat signature, some parts of it are more active than others. So it is my belief that those of the AB/DL community, have at least one part of the brain that is active. I honestly think it has nothing to do with childhood, but more the brain has linked a inanimate object (diapers). That when used or worn, or even some cases thought of, our brain releases endorphins, for that happy comforting feeling. I hope to study this more thoroughly once I have my PhD.
