Hi Sabrina, and welcome back!
It's awesome to help you once again here on the Disney Parks Moms Panel!
The height restrictions are helpful to make sure that all children enjoying those attractions are safe, and those safety conditions are altered when adults have children on their laps. The great news is that you and your nephew can start planning for a next trip in the future for his inaugural adventures at those attractions. I'm sure your family can make the countdown fun!
For this trip, there are many thrilling attractions that will be safe for your sweet nephew, like the all new and super fun
Alien Swirling Saucers and
The Barnstormer.
Here is a custom made list of all the amazing attractions and experiences that you and your nephew will be able enjoy together.
To spice this adventure up,
The Pirates League might also be a very exciting experience that is open to Guests that have more than 3 years of age.
For those attractions that he will be discovering on future trips, such as Splash Mountain, your family can use the
Rider Switch Service to avoid waiting on the regular line twice.
I am sure that this trip will be amazing for you and your nephew! If you ever need more advice, please, stop by. We love to help!
May the magic be with you,
Julie
