Hi there, Veronica!
Welcome to the Disney Parks Moms Panel, and thanks for stopping by with your great question. Disneyland Resort is very accommodating when it comes to children of all ages. You will find convenient
Baby Care Centers located in Disneyland Park and Disney California Adventure Park which offer private and quiet spaces for feeding and changing little ones. These centers also offer a variety of items like bottles, diapers, and sunscreen, for example, that you can purchase with a credit card if you need them in a pinch. Unfortunately due to the personal nature of breast pumps, these are not provided at the Resort. You are more than welcome to bring your own pump and use it at the Baby Care Centers as outlets and private areas are provided. If you need to store your pump during your visit, you can use one of the locker rentals located in each park or between the parks in the esplanade. I love these lockers, because you can use them throughout the day as many times as you'd like for one low price.
If you will be traveling with a little one and will need a
stroller for your visit, you are able to rent one directly outside the gates of Disneyland Park. Many Guests love the convenience of these rentals, because it takes the hassle out of bringing your own if you already have a lot of items to take when you travel.
Keep in mind you can also take infants on any attraction that does not have a posted height requirement. My son visited the Disneyland Resort at 10 months old and had a wonderful time on classics like Dumbo the Flying Elephant, "it's a small world," and Peter Pan's Flight to name a few.
I hope this helps, and I can't wait for you to make magical memories at the Happiest Place on Earth!
