Bring:
toothbrush, toothpaste, soap, shampoo, conditioner, etc.
Brush, comb, hair spray, hair ties, bobby pins, flat iron (if you use one)
underwear, bras, sports bras, socks, your cheer shoes, and flip flops for the shower, your camp clothes (most teams have outfits for each day that all match), a camera, money (if you want to buy anything there), water, or water bottle, snacks.
I take my stuff if a suit case and my cheer bag. It really doesn't matter though.
It depends on the camp, but most camps feed you breakfast lunch and dinner. Ask your cheer coach about it, or google the camp that you're going to.
You will have so much fun!! good luck
