Hi Tim,
There are many attractions that your little girl will be able to enjoy. The rides at Disney have minimum height requirements as opposed to age restrictions. You will be able to bring her on any of the attractions that don't have a minimum height requirement. She can sit next to you or you can hold her on quite a few of the rides. Some examples are: It's a Small World, The Many Adventures of Winnie the Pooh, Pirates of the Caribbean, Peter Pan's Flight, Buzz Lightyear's Space Ranger Spin (put her on your lap and have her help you "shoot the laser"), Kilimanjaro Safari, Journey into Imagination, The Seas with Nemo and Friends, Spaceship Earth and many more.
To get an idea of which attractions your little one can ride, see this link:
HERE . You'll need to select the Height arrow on the left and choose the different height criteria for your daughter.
In addition, the park maps have an icon of a person with a measuring stick next to them if the attraction has minimum height requirements. This will make it easy for you to decide what you can bring her on.
Have a wonderful vacation,
Kaylene
