Hi there Linda!
Thanks for bringing another great question to the Disney Parks Moms Panel. I'm so excited you plan on taking your little one to the Most Magical Place on Earth! My son's first trip to the Walt Disney World Resort was also at 10 months old, and there were so many wonderful experiences and attractions available to him.
Know that any attraction without a posted height requirement means you can ride with him or her beside you or on your lap. You can check the
height requirements for every attraction online or on the
My Disney Experience mobile app. While most of the attractions without a height requirement can be found in Magic Kingdom Park, rest assured that you will be able to experience attractions in every one of the four theme parks with your little one. Some of my son's favorite attractions were Dumbo the Flying Elephant, Peter Pan's Flight, "it's a small world," Frozen Ever After, and The Seas with Nemo & Friends to name just a few. Plus, don't forget about Character interactions and entertainment throughout your days as well. My son loved hearing live music performances in Epcot or meeting some of his favorite Characters in Disney's Hollywood Studios and Disney's Animal Kingdom.
I also wanted to inform you about the fantastic Baby Care Centers provided to infants and toddlers at each Walt Disney Resort theme park. These are areas where you can get some privacy with your baby if you need to change or feed them. You can also find replacement supplies if you lost or forgot anything for your child.
I hope this helps, and feel free to return if you have any other questions. Have a magical day!
