Hello, Jessica! Yay! I am so excited that you will be visiting the Disneyland Resort with your little one!
You will be pleased to know that there are oodles of attractions that don't have height requirements which means that even infants can ride with their parents. If you filter the
Attractions page by "Any Height" you will see the long list of attractions that you can ride with your toddler. My best suggestions are "it's a small world," Dumbo the Flying Elephant, Jungle Cruise, Peter Pan's Flight, The Little Mermaid ~ Ariel's Undersea Adventure, and The Many Adventures of Winnie the Pooh. When my daughter was 1 year old, she also really enjoyed carousels so make sure to take a spin on King Arthur Carrousel in Disneyland Park and King Triton's Carousel in Disney California Adventure Park.
When it's time for a diaper change or to feed your child, head to a
Baby Care Center - there is one located in each park. They have spacious and comfy changing tables, highchairs, rocking chairs, and they even sell baby essentials in case you run out of anything during your visit.
I hope this helps! Have a magnificent time at the Happiest Place on Earth!
