Kim Kardashian [1] went the extra mile to make her son Saint feel special [2] for his birthday. On Saturday, the mogul threw her little one — who turned 4 on Dec. 5 — a dinosaur-themed party so elaborate, it could easily double as the set of Jurassic World 3 [3]. Kim took her Instagram followers on a tour of the outdoor gathering, sharing photos and videos of prehistoric-inspired sweets, play stations, and food trucks. "Happy birthday, Sainty!" she captioned a clip. "I love you."

The get-together was a family affair as Saint spent time with siblings North, 6, Chicago, 1, and 6-month-old Psalm. Khloé Kardashian and daughter True [4] also took part in the festivities and joined other guests in a bouncy house. The celebration continued as attendees enjoyed a rainbow cake filled with M&M's before taking home their own children's Yeezy slides from Kanye West's shoe line [5].
