Oh! Well no problem. AD/BL stands for Adult Baby and Diaper Lover. Basically it's when someone enjoys 'roleplaying' or acting as a younger age. People who take care of ABs are called either 'Caretakers' or 'Mommies/Daddies'. I was pointing out that while Vinyl isn't exactly an AB (Or in the ponyverse, a 'Forever Foal') Octamom seems like a caretaker.
Not to mention she must have a degree in science and math as to calculate the weight of Vinyl Scratch and the how fast she'd fall down and how fast she'd need to get the booties and diapers out to get her in them without missing a beat.
