Yes...I meant what you bring in your backpack, fannie pack, etc....what you need to get thru the day! Thanks everyone!!
This will depend on your group. I have 2 LOs so I bring a ton more into the parks now than I did when it was just me. There are minimalists and pack horses

.
I bring one backpack with the following for my whole family of 4:
extra outfit x 2 (for kids)
diapers
wipes
hand sanitizer
sunscreen
sunglasses x 4
snacks
water bottle x 2 ( we refill through the day)
emergency kit (bandaids, Tylenol, advil, neo to go, tide to go)
bib
lightweight blanket
click sharpies and something for autographs x 2
iPhone
bodyglide
stickers and other line/meal distractions
camera and extra battery
APs and KTTW if overnight trip
CC (Disney Visa only)
cash
Mickey and Minnie or Ariel dolls
we also have a stroller. We often will leave a portion of these items in the stroller in a small bag to lighten the backpack. DH and I trade off wearing the pack and I keep all of the $, passes, other cards in a pocket with FPs (I don't like lanyards). We don't pin trade and don't have the kids carry anything yet b/c of their young ages. That might change in the future.
Oh, and I do an itinerary in my phone so I don't bring any papers.
