Yes, at both Disneyland Resort in California and Walt Disney World in Florida, children under the age of 3 (ages 0, 1, and 2) receive free admission. They do not require a park ticket or a park reservation to enter. Furthermore, these "infants and toddlers" can also eat for free at Disney’s "all-you-care-to-enjoy" buffet and family-style restaurants if they share from an adult’s plate. Once a child turns 3, they are required to have a "child" ticket, which is slightly discounted compared to adult pricing (ages 10+). This policy makes the toddler years a very popular time for families to visit, as it significantly reduces the overall cost of the vacation. Disney is also incredibly well-equipped for babies, offering "Baby Care Centers" in every park that provide private nursing rooms, changing tables, and high chairs, ensuring that even the youngest guests—who are attending for free—have their needs met in a comfortable, air-conditioned environment.
