Sure, babies in costume are cute, but none of them are cuter than sweet, sleepy Joey of Laura Izumikawa’s NAPTIME WITH JOEY! (Except YOUR baby, of course.) The Instagram sensation now has a book filled with some of Joey’s classic looks, plus tons of new ones! We defy you to look at these pictures without your ovaries exploding–even if you’re a guy.

Need some Halloween costume or cosplay inspiration? Check out Joey as Eleven from Netflix’s hit Stranger Things!
