Case in point: Donald Trump Jr. and his wife Vanessa posted to their social media accounts photos of their sons Spencer, 5, and Tristan, 6, saluting, wearing camouflage army fatigue costumes topped with a helmet.
The couple's daughter Chloe, 3, was photographed, also saluting, wearing a police officer costume.
And Vanessa captioned her Twitter post, "My kiddies are getting into the 2017 Halloween spirit!"
Last month, Chloe got a head start on her Halloween costume planning, with her dad posting a photo on Instagram of her in a mask of her grandfather.
"If this isn't the funniest thing I've ever seen, I don't know what is," Donald Jr. wrote. "Chloe apparently has decided on her Halloween costume... and she loves her Grandpa.
President Trump on Friday welcomed the children of White House reporters into the Oval Office for some early Halloween treats.
More than a dozen costumed kids, including little witches and Princess Leias, a pint-sized Darth Vader, and a purple-haired unicorn gathered around the Resolute Desk, where the president handed out little boxes of White House Hershey's Kisses.
"I cannot believe the media produced such beautiful kids. How the media did this, I don't know," he said as he welcomed the kids to join him around his desk.
Trump also joked with the kids about their parents' professions. "You going to grow up to be like your parents?" he asked. "Don't answer. That can only get me in trouble, that question," he joked.
