Since he wanted to feel the need to regress into an earlier childhood, I created a list for him to fulfill before contacting me.

#1). Batman / Robin, or other colorful character underwear BVD's along with jammies.

#2). Colorful diapers with prints on the outside.

#3). Plastic pants to cover these in case of a leak.

I instructed him to email me, when he gathered everything I requested, which took around 4 days.
