Hi, Carolyn!
Welcome to the Disney Parks Moms Panel, and thanks for your wonderful question about exploring the theme parks with a baby! I’m a huge fan of introducing little ones to the magic of Disney early on, so I’ve been taking my own son to the parks since he was just a few months old.
Yes, there are lots of attractions your 7-month-old can ride at Epcot, including Living with the Land, Journey Into Imagination With Figment, Maelstrom, Spaceship Earth, and The Seas with Nemo & Friends, just to name a handful. If it is labeled as being suitable for "any height” or there is not a minimum height requirement posted at an attraction, then your baby may ride. Visit Walt Disney World’s interactive
attractions page online and sort the height field by “Any Height” to see a complete list of attractions you can experience with your infant at any and all of the theme parks.
I hope this helps, Carolyn, and that you have a perfectly pixie-dusted visit to the Walt Disney World Resort with your little one! Please write back with any other questions you may have as you continue to plan.
Wishing you magic,
Courtney
