Greetings, Britni!
Thanks for stopping by the Disney Parks Moms Panel with your great question. Disneyland Resort is very accommodating when it comes to families with infants and toddlers as well as mothers who nurse or pump.
I'm happy to let you know that you can utilize the
Baby Care Centers located in Disneyland Park and Disney California Adventure Park to pump in private, comfortable spaces. Although there is nowhere to specifically store expressed milk in the parks, you may head to
First Aid at either park to store your pump as it is considered a "medical device" which can be left here during your park day. For milk storage, I recommend bringing a small cooler with ice packs that can fit in the convenient
locker rentals at each park. These lockers can be accessed all day for one low price. You can also store your pump in these lockers if it is more convenient for you. I liked to grab some complimentary ice cups from Quick Service restaurants in the park to keep bottles cold in my cooler throughout the day if my ice packs started to melt.
Taking an infant or toddler to the Disneyland Resort is so much fun. I loved seeing the joy in my son's eyes as he experienced his first attractions and Character meetings. Since little ones can ride any
attraction without a height requirement, there is really so much for them to experience at these early ages.
I hope this helps, and please return if you have any other questions!
