Hi there, Myrna!
Thanks for visiting the Disney Parks Moms Panel with your question. Your son is going to have an unforgettable birthday at the Happiest Place on Earth. If he is already three years old at the time of your visit, he will need a ticket to enter the park. You can
purchase tickets online or on the
Disneyland app. Fortunately, a child ticket for ages 3-9 costs less than an adult ticket.
Celebrating a birthday at the Disneyland Resort is so much fun. Make sure you stop by City Hall in Disneyland Park to pick up a complimentary birthday button for your son. Have him wear this throughout your vacation to receive special birthday greetings from Characters and Cast Members.
Once your child is three years old you can also schedule them for a magical transformation at the
Bibbidi Bobbidi Boutique in Disneyland Park. We recently took my son for "The Knight Package" where he was given a shield, sword, and glitter in his hair by a Fairy Godmother-in-Training. He loved showing off his new look throughout the day.
I hope this helps, and in the meantime I wish your son a very merry UNbirthday!
