Rick decided to make himself an infant. A newborn, more precisely. That seemed the most interesting in his opinion. Seeing himself as older than he was might be scary as the effects of age might be appalling. Whereas being a newborn meant experiencing something he could not remember. At worst, he'd know he'd grow up with a better appearance. And he could also think about the fact that all newborns looked ugly as a rule as a consolation. So he pressed the button and waited.
He did not have to wait long. The change was instantaneous. Before he knew it, Rick was floating in a sea of cloth that used to be his pwn clothes. He was on his back and quickly realised he was helpless, and how much so. He was unbelievably weak and his movements either unresponsive or jerky. Or simply so sluggish he might not have tried at all. Rick could only observe the ceiling, his new regressed body keeping him from turning his head to look at anything else. Luckily, his vocal chords, like any other infant's, worked well enough to scream out for help. Which he did, caught yup in his own panic. His infant instincts took over and imposed to his still adult mind how much he needed someone. And someone did come. A woman dressed like a nurse who shushed him, told him he'd be given the antidote soon and that he should rest for now. She placed him in a wicker basket with nice blankets, as well as a diaper as a precautionary measure, and told him to wait a bit and that these things happened all the time. Reassured, Rick did not even notice falling asleep. As for the nurse, she informed another that they had caught another one. The resort had a deal with the fay world and they sometimes sent regressed or transformed humans over the fay realm. Low on birthrates and humans being so malleable in terms of transformations, they made the perfect offspring and pets to adopt. The fay traders paid hefty sums for these transformed humans and humans soon found buyers. The younger the better and as Rick slept on, he did not even notice his cradle decorated with flowers and nice embroidered blankets being added to it. Presentation increased the price tag, after all. By the time Rick awoke, he'd be in a truly different world.
