Hey there, Hi there, Ho there, Elsy!
You're as welcome as can be here at the Disney Parks Moms Panel, so thanks for bringing your great question. You and your little one are going to create such magical memories together at the Happiest Place on Earth!
You are more than welcome to bring baby formula into the Disneyland Resort in any way that is convenient for you. Many Guests choose to bring the small containers of powdered formula as they come packaged from the store. Since
outside food and beverages are allowed (with certain restrictions), you will have no problem bringing in formula, bottles, or baby food pouches into the parks if your child needs it during the day. To give you freedom during the day, I recommend
renting a locker in either park or in the esplanade between the parks to store belongings such as formula, a change of clothes, sunscreen, or anything else for your baby that you don't want to carry all day. These lockers are one low price, and you can access them all day as many times as you'd like. Ever since I started bringing my son to the parks, I ALWAYS get a locker. Plus, it's great for storing souvenirs and purchases we make as well.
I also recommend stopping by the
Baby Care Centers located in each park when it is time to prepare your bottles, feed, and change your baby. These locations are perfect when you want a semi-private space to take care of your little one. There are even microwaves available if you need to warm food, water, or bottles.
Did you know that there are SO many
attractions your baby can ride with you? Any attraction that does not have a posted height requirement is safe for even the littlest infant Guests. At this age my son loved the family-friendly rides in Fantasyland as well as watching entertainment and musical acts throughout both parks.
I hope this helps, and See ya Real Soon!
