However, the start of Jenner's 18th birthday weekend has been notably, well, mature.

The reality star kicked things off by giving back. She shared a photo of herself at Children's Hospital L.A. standing next to a tiered cart piled high with goodie bags, writing, "Let the birthday celebrations begin! First stop: @childrensla"

Even Kris and Caitlyn got in on the action.
