Hi, Gabriela!
Welcome to the Disneyland Resort. Mickey Mouse and all his pals cannot wait to meet you and your family!
You are certainly allowed to bring all of your baby's necessities into the theme parks including baby food, diapers, wipes, bottles, and any other items you might need. Each park will have a
Baby Care Center that you might find handy. These centers are the perfect place to feed and change your baby. The Baby Care Centers also sell any items that you might need - including all the baby basics!
I am guessing you plan to use a stroller for your baby. You are welcome to bring your own, or
strollers are available to rent just outside the main gate to the Disneyland Park. Rental strollers can be used for the entire day, even between Disneyland Park and
Disney California Adventure Park, but you may not take the rentals back to your resort.
I hope your family has a magical visit to the Happiest Place on Earth!
Cathy
