As an ABDL, my favorite thing of all is to fill my diaper with a firm hot poop and stand there, enjoying the way it feels as the diaper caresses the poop against my butt. It is one of my clearest memories of being a toddler, and I loved doing it then. Sometimes I sway from side-to-side, another fun thing I did as a toddler in a poopy diaper, and I enjoy the way the load shifts on my butt from the left to the right and vice-versa.
