Hi Jesse,
Thanks for stopping by to see us here at the Disney Parks Moms Panel with your question!
I'm so glad to tell you that your infant is considered a special guest of Mickey Mouse himself and is admitted to all Walt Disney World Resort theme parks at no charge until the age of three. You may carry your infant on to attractions that do not have a height requirement and a FastPass+ reservation is not required for your little one. I would include your infant in any Advance Dining Reservations you may have throughout the resort if you intend to bring them along to ensure that the restaurant staff can ensure that you have enough space at the table for a high chair for your baby.
While I have your attention, I thought I'd mention a fantastic service available for families with smaller children, or even adults that don't want to ride. The
Rider Switch Service gives you an opportunity to divide into two groups, allow the first group to experience an attraction, then allow the second group the experience the attraction with a shorter wait time. Please ensure that all members of your party are together when you approach a cast member to ask about this service.
Jesse, I hope you and your family have a magical time during your upcoming Walt Disney World Resort vacation!
Best Wishes,
Amy S.
