Hi Yadira, welcome to planDisney!
How exciting! The Disneyland Resort is my absolute favorite place to
celebrate birthdays. Be sure to visit City Hall on
Main Street, U.S.A. in
Disneyland Park, or at Guest Services in
Disney California Adventure Park to pick up your complimentary birthday button for your son!
But back to your main question. Children ages three and above need a
theme park ticket to enter the parks. As your son will be three years old on November 11, 2022, if you are planning to visit on that day, he will need a ticket to enter the parks.
Before I let you go, I do want to mention that the
Baby Care Centers are amazing and worth a visit! My wife and I used them often for our little ones. They offer a clean and comfortable facility with changing rooms, nursing rooms, a feeding area with high chairs, and more. At Disneyland Park, it's located at the end of Main Street, U.S.A., next to
First Aid. At Disney California Adventure Park, the baby care center is located next to
Ghirardelli Soda Fountain and Chocolate Shop, across from
The Bakery Tour in Pacific Wharf.
If you have any other questions at all, please visit us again!
See ya real soon!
