It’s not rare for adults to go through a sense of nostalgia as times. It’s not even rare to never want to grow up, keeping that childhood innocence with you as you get older. But for Stanley, the “adult baby,” the phrase “never grow up” is taken as literal as it comes.

Stanley sleeps in a giant crib (that he built himself,) plays Legos in a baby play area, gets fed with a bottle and is even creating his own gigantic highchair. No matter how psychologically complicated it may appear, he claims he is just “recapturing the moments of a simpler time.”

The video clip comes from an episode of National Geographic Channel’s “Taboo,” and follows Stanley who acts like an adult out in the real world, but in the privacy of his home, slips into baby mode.
