Mr. Miller has thus far adamantly denied the accusations. "Totally false. The only thing I'm guilty of is becoming more efficient at parenting," said Mr. Miller. "If the kids need discipline, I just cancel their allowance on Venmo. I've developed an escalating series of angry ‘gifs‘ to send when they are treading on thin ice. And I have them text me a picture of their homework when it's done. Honestly, I'm more on top of it than I've ever been."
