Hello Fabiola and welcome to planDisney!
Thanks for dropping by with such an excellent question!
I'm happy to report that your entire family is welcome to visit the Disneyland Resort together. The state guideline that you are referring to states that
groups of no more than three households may visit the theme park together. You are welcome to bring all individuals from your household!
While you do not need to purchase a ticket for your little one under the age of 3, you will need to purchase tickets for the rest of your household. Also, make sure to secure a
Theme Park Reservation for each member of your party over the age of 3. This reservation is required in addition to your valid admission. I recommend checking the
Availability Calendar prior to purchasing your tickets to confirm your desired date and theme park are available.
I hope this answers your question! Please head back to planDisney if you think of any more!
