Hi Donavan,
Thank you so much for visiting the Disney Parks Moms Panel with your question! I remember heading to Walt Disney World with my daughter when she was a toddler. It was so wonderful to watch her explore and be enchanted by Walt Disney World.
The limits on certain attractions at Walt Disney World are set by height rather than age. There is a wonderful
Disney Parks Blog post with height requirements for attractions at Magic Kingdom, and links for those at Epcot, Disney's Hollywood Studios, and Disney's Animal Kingdom are available at the end of that blog post. These charts can help you see which attractions are available to your little one. Also remember that the Disney theme parks are filled with amazing shows that your little one can experience. At two years old, my daughter was on the move and ready to take in so much! Some of her favorites at that time were it's a small world in Magic Kingdom, Journey into Imagination with Figment at Epcot,
Disney Junior - Live on Stage! at Disney's Hollywood Studios, and a ride on the
Wildlife Express Train to Rafiki's Planet Watch to interact with animals at Affection Section at Disney's Animal Kingdom.
Do check out the planning page for
Walt Disney World with small children. This site will give you many ideas for planning your magical vacation with a small child.
I hope that these thoughts are helpful for you, Donavan. Have great time planning your vacation, and please do not hesitate to ask if you have any further questions!
