About changing a birth date for a child
To change a birth date to any age below 13*, the account must be a member of a Family Sharing group, and the family organiser must approve the change. Follow the steps to change a birth date on the web. You can also create a new Apple Account for a child.
To change a birth date of any child account set to an age below 13*, you may have to wait for the account to naturally age up. If you see “your birth date cannot be changed to this date”, you can’t change to a birth date that would no longer be a child account.*
