Hi there, Jayne!
Welcome to the Disney Parks Moms Panel!
Each Walt Disney World theme park has a
Baby Care Center that is equipped to handle quick changes and supplies. They are open during the park's operating hours and is a free amenity that offers a kitchen with a microwave and sink, chairs, television, and sofa. There is also a shop that provides formula, over the counter medications, diapers, and any other supplies that you can purchase for your little Princess.
Unfortunately, there is no place for her to lay and rest, but you are welcomed to sit with her in the Baby Care Center while she rests.
Also, you can exit the park, take a nap in your resort, grab a bite to eat, and re-enter the park later in the day for no additional charge. This will allow you and your family to rest and rejoin the fun at the Magic Kingdom!
Jayne, Thanks for visiting the Disney Parks Moms Panel! If you need more help, please stop by again soon!
Have a magical vacation,
Korliss
