Hello Alison,
I bet you are getting so excited for your upcoming vacation! Bringing a toddler to Walt Disney World is such a magical experience. It really makes you slow down and see all of the wonders through little eyes. Your daughter probably won't remember her first visit, but you'll remember it all, and the memories that you make will be priceless. Bonus: your little travel partner gets to enter the parks for free!
Don't worry about bringing documents to prove your daughter's age. Cast members realize that children come in all sizes. If a cast member does ask your daughter's age, just let them know she's two, and you'll be on your way to a day of fun!
Be sure to stop by Guest Relations in any park and pick up a complimentary "First Visit" button for your child. It's a fun keepsake, and cast members will love welcoming you to Walt Disney World. If you find you need a break from the crowds and noise of the parks, be sure to check out the
Baby Care Centers. They are quiet, air conditioned spaces in each park for parents with infants and toddlers. You'll find rooms for feeding, changing diapers, or just escaping for a few minutes to recharge.
Hope this helps. Have a magical vacation!
