OnThe Drew Barrymore ShowMonday, the CNN anchor, 54, shared that his 18-month-old dressed as a makeshift Batman for the holiday. Calling it a “weird picture,” Cooper showcased a snapshot in which Wyatt stands in a Batman mask and cape while holding a toy vacuum.

“Let me just quickly explain. Chip Kidd, who did the book jacket for my book, is an amazing designer. He has an incredible Batman collection and his mom, in the ’60s, made him that Batman cape,” theVanderbilt: The Rise and Fall of an American Dynastyauthor says.

“So Chip gave me the cape that he had as a kid and one of those vintage Batman masks from when I was a kid,” says Cooper, adding, “And my son is obsessed with cleaning products. He is obsessed. It doesn’t actually vacuum, it just makes the sound of a vacuum. And it is the greatest gift he has ever received in his life.”

“I suddenly think like, ‘Oh my God, there’s going to be a time when he won’t let me kiss his face all over or hold his hand even.’ I just want to rub his tummy right now as much as I can, because I know at a certain point he’ll be like, ‘Just get away from me,’ " said Cooper.
