We just got back from
Disneyland and took these things for our DD 2 1/2.
Sippy Cup-one of the cheapy ones from walmart, we only used this for milk in the mornings it only left the hotel once. Once in the park she drank a lot of ice water either from our water bottles or from the cups with staws.
Small 3oz bottle of dish detergent-for washing the sippy out.
2 Blankies-one personal favorite that did not leave the hotel room and one lighter weight one that we used as a cover for extra shade or a light blanket for her naps.
2 stuffed toys-One for the park and one for the hotel. Though truth be told after the first day she carried around the little princess minnie we bought the first day.
Lots of extra ziplock bags for messes or wet clothing.
I brought and outfit for each day and then three extra for just in case-we wound up using all of them.
Pull ups-she's potty trained for the day so we just used these at night for her
Lot's of underwear and socks
2 hats, sunscreen and a pair of sunglasses
Toiletries-tooth brush, tooth paste, shampoo, loofah.
Things we brought but didn't really need:
Coloring book and crayons-this worked for us as the sit down restaurants we stayed at gave her crayons and something to draw on and we were a large group so at the quick service there was always someone to keep her entertained.
Once we arrived we picked up banana's, granola bars and soy milk to keep in the room and use as snacks. We bought one of the power packs and it lasted us a day and a half with all the little treats in it as she couldn't eat the whole thing in one sitting but she's light eater.
Things I wish I had remembered to grab:
Pedialyte-it was on my list but did not get packed, we really could have used it as an incentive to drink more water as DD doens't get many flavored drinks.
