Hi Christine!
We have been bringing our kids to Walt Disney World since they were babies, so I have plenty of suggestions for fun activities for a one-year-old.
At the Magic Kingdom, your little guy will love "it's a small world," The Many Adventures of Winnie the Pooh and Cinderella's Golden Carrousel. He will also love Playhouse Disney at Disney's Hollywood Studios, Animal Affection Station at Animal Kingdom and The Seas with Nemo and Friends at Epcot.
The attractions at Walt Disney World have height restrictions, but no age restrictions. Therefore, your one-year-old can go on any ride that doesn't have a minimum height requirement. Check out the
Attractions page and click on "Any Height" under the height requirement check box. This will provide you with a full listing of the attractions at al four parks that your little guy can enjoy.
I also recommend checking out the
Little Ones at Disney guide for more tips for traveling to the most magical place on earth with little ones.
Magically,
Stacy
