Greetings Brianna!
Welcome to the Disney Parks Moms Panel. I'm so excited just thinking about your family's upcoming visit to the Happiest Place on Earth. As the mom of a three year old, we have had plenty of wonderful experiences over the last few years taking our son to the Disneyland Resort. There are so many attractions that the three of you will be able to ride sitting together as a family as my husband and I have with our son. Did you know that you can take your son on any attraction that does not have a height requirement? Most of these will also fit the three of you in one seat or row. Some of our favorites recently to experience together were Haunted Mansion, "it's a small world," The Little Mermaid ~ Ariel's Undersea Adventure, and Pirates of the Caribbean.
Since you said your son is 32" tall, you will also be able to experience even more fun attractions together like
Luigi's Rollickin Roadsters and
Mater's Junkyard Jamboree at Disney California Adventure Park and
Autopia at Disneyland Park.
Don't also forget about some of the wonderful modes of transportation around the Disneyland Resort. My son at this age absolutely loved the Disneyland Monorail, the Disneyland Railroad, and the Red Car Trolley. He also adored meeting some of his favorite familiar Characters.
I just know you are going to have an unforgettable experience together. Have a Fantasmic day!
