Hi Brandon! Welcome to planDisney, and thank you for submitting your question to us!
I am a parent of a Mouseketeer under three years old as well, and at this age, they are considered to be a "guest of Mickey". At this age, they do not need a theme park reservation or a ticket to enter any of the theme parks. If you are making table service reservations for restaurants, they do need to be added to your list when you make your reservation for seating purposes.
Dining with Mouseketeers at Walt Disney World Resort is fun, but can be a daunting task, especially if you have picky eaters! Fortunately, several restaurants offer a buffet or meals served family-style that even the pickiest eaters will enjoy! Some of my family's favorites include
Garden Grill Restaurant at EPCOT,
The Crystal Palace at Disney's Magic Kingdom Park, and
1900 Park Fare at Disney's Grand Floridian Resort & Spa. The best part about all three of these restaurants is that they are all character meals! You'll have the opportunity to knock out meeting some characters while enjoying a delicious meal (and you don't even have to leave your table!). It's a win-win!
One final important tip I want to talk about is the
Baby Care Centers. They are the perfect place to take your little Mouseketeer for diaper changes, feeds, and if they just need a quick break from all the hustle and bustle. If you run out of diapers and wipes, you can also purchase them here. The Magic Kingdom Baby Care Center is my absolute favorite!
Brandon, I hope all of this information was helpful! Thank you again for stopping by planDisney. Have a magical visit to Walt Disney World!
Magic Awaits!
