Hey Howdy Hey Jonathan and welcome to planDisney!
Thank you for stopping by with your specific question about entering the parks with a medical issue. Walt Disney World Resort is a place for families to enjoy the experience of a Magical vacation with the consideration of mobility and medical issues. I will be happy to give you more information on entering the parks.
I am happy to report that entering the park with diapers should not be an issue at all. You can check out the
list of prohibited items in Walt Disney World Property Rules, but as long as nothing you plan to bring is prohibited, you should be all set. I will forewarn you that bringing in a bag is completely fine to the parks, you may have to stop for extra inspection before entering the parks but should have no issue with being allowed the diapers in your situation.
Considering the time of year you will be in Walt Disney World, you may have the opportunity to experience the
EPCOT International Food and Wine Festival. This is one experience you will not want to miss. Throughout EPCOT you will find ways to celebrate the end of summer and fall months with unique food and drink offerings as well as top-notch entertainment. Make sure to keep up with all that is happening this year over at
Disney Parks Blog to better plan for your upcoming trip!
Have a Magical day,
Nick
