Hey there, Angela!
Thanks so much for stopping by the Disney Parks Moms Panel with your fantastic question. As the mother of a four year old who has been vacationing to the Disneyland Resort since he was an infant, I can say with absolute certainty there are going to be so many amazing experiences for your toddler at the Disneyland Resort.
Many of the most classic
attractions at Disneyland Park and Disney California Adventure Park do not have a listed height requirement which means they are safe for even the littlest Guests, including infants and toddlers. As a toddler my son was always captivated by "it's a small world," Dumbo the Flying Elephant, the Disneyland Railroad, Mad Tea Party, The Little Mermaid ~ Ariel's Undersea Adventure, and Pirates of the Caribbean to name just a few of the many family-friendly attractions he experienced. Little ones this age also love transportation of any kind so something as simple as a trip down Main Street in a vintage fire engine or taking a relaxing ride on the Mark Twain Riverboat can be something extraordinary for them. Don't forget that kids this age are also big fans of meeting some of their favorite Characters throughout both parks. Keep an eye on the
Disneyland app each day for locations and times where Characters are meeting with Guests.
With little ones who are still in diapers or who are in the middle of potty training, you will definitely want to visit the Baby Care Centers located in each park. They provide semi-private spaces to change or feed little ones as well as tiny toilets perfect for tots. This is also where you can purchase any essentials you may have forgotten like diapers and pacifiers, for example.
I hope this helps, and please return if you have any other questions. Have a Zip-a-Dee-Doo-Dah day!
