Whether you need a separate Disney account for your child depends largely on their age and how much autonomy you want them to have within the parks. For children under the age of 13, Disney policy prohibits them from having their own independent "MyDisney" account. Instead, you must create a managed profile for them within your own account's "Family & Friends" list. This allows you to link their park tickets, make dining reservations, and manage their Lightning Lane entries on their behalf. If your child is 13 or older, they are eligible to create their own independent account. This is often beneficial for teenagers who might want to use the app on their own phones to check wait times or join virtual queues while exploring the park separately from the rest of the group. However, even for older children, many parents prefer to keep them as managed profiles to ensure all plans remain centralized and easy to view in one place. If you do decide to let them have their own account, you can "invite" their account to connect with yours so you can still share plans and photo pass images.
