Quoting ~Raylan's Mama~:" Undies and has he at least been introduced to the potty?"
He actually was using it for a while but had issues holding his poop in and had to get an enema. It was extremely traumatic.
Then his dad went to jail for a while and he completely regressed due to all the changes in his life.
- but his life now is incredibly stable so i wanna give it another go.
