I know not many people are going to see that, but something just occurred to me and a lot of things clicked into place. My preferred 'little' head space is a toddler old enough to be potty trained, but is resistant to it. So basically making a conscious choice to keep wearing diapers. I think that's a big part of why I'm wary of a lot of 'forced' scenarios and prefer it to just be something the characters are enjoying.
