The Trumps always celebrate in style and the youngest members of the clan didn't miss a moment when ringing in the new year.
Barron sported black-tie attire as he accompanied his parents, Donald and Melania Trump, at their Mar-a-Lago New Year's Eve party, where tickets reportedly went for $600 for members, and $750 for guests.
Ivanka Trump and Jared Kushner followed closely behind at the West Palm Beach resort with their two elder kids Arabella and Joseph. The mother of three shared a photo of the group in color-coordinated outfits on Instagram.
Donald Trump Jr. tweeted photos from a family fishing trip and dinner and a night in with his kids, Donald Trump III, Spencer and Chloe.
The father of five, who celebrated his 40th birthday on New Year's Eve, also shared a cute video of 3-year-old Chloe singing him "Happy Birthday."
Donald Jr. was also photographed earlier in the day building sand castles and playing golf with his kids at his dad's Florida estate.
While Eric and Lara Trump's son, Eric "Luke" Trump, might be too young to stay up until midnight at only 4 months old, the pair posted photos of them on the red carpet at Mar-a-Lago and enjoying a fireworks display.
