We all know what diapers are for. As much as we wish they could, they don't hold an infinite amount though. Eventually they need to be changed, especially if you're a certain little super soaker. Regressing means your adult-sized bladder shrinks to a baby-sized one, but the contents don't shrink, so expect a super soggy diaper incoming.
I wanted to get this pic done because IRL I do pee a lot. X3 I can sog up a diaper quickly, and always wake up soaked after sleeping through the night.
