--As the title for the series says, this focuses on being age regressing to a baby (0 to about 3 years of age) And the upsides and downsides will be more focused base on that idea.
---Also, I understand that some of my watchers like age regression , and may not find there is any downsides, I'm basing this off my character who really wasn't expecting to be turned into a baby and finding the situation he's in to be really embarrassing. So I understand not everyone will agree with these, after all, to each their own. XD
