Hi Nicole,
Your little princess won't need any identification to enjoy her
Walt Disney World vacation with the rest of you. I visited with my daughter dozens of times before she turned 3, and even though she was tall for her age, I never had anyone question me or her. I had a small laminated birth certificate card that I always carried for my children when they were little, just in case, but never needed to show it at Walt Disney World.
Even without a ticket, your daughter will be able to accompany you on many rides and attractions, including those for which you have
FastPass+ reservations, just as long as it is a ride that has no height restrictions. You'll find lots of tips and a list of age-appropriate rides in the helpful
Guide for Visiting with Pre-Schoolers and Little Ones linked here.
And if you need a place to change, feed or rest with your daughter, make sure you check out the
Baby Care Centers located in each of the four parks.
Thanks for stopping by the Disney Parks Moms Panel, Nicole. Please let us know if we answer any other questions for you as you make your plans. We're always happy to share our experiences with other guests.
Enjoy!
Wilma
