(This is based off of my AO3 AU of these four characters and their experiences with AB/DL themselves. You can choose which one to rp out of the four, but I'd recommend checking out my two fanfics this is based on: 'One Job, Multiple Secrets' and 'The Consequences of her Story' on AO3.)

Yutaka: Still getting introduced to the whole concept, but wants to get taken care of by Minami. Minami: Works at the daycare. Loves seeing Yutaka as a little and taking care of her due to Hiyori's influence. Patricia: A little who loves acting like a baby, and is an absolute bundle of energy in the daycare. Hiyori: Co-owns the daycare with her cousin. Both into diapers herself and taking care of others, and is Patricia's main caregiver.
