From the article below.
Invite people to join your family
If you haven't already, you can create an Apple ID for a child and add them to your group. If your family member already has an Apple ID, use the steps below to add someone to your family group. You can be a part of only one family at a time.
If your family member is with you, they can enter their Apple ID password on your device to accept the invitation. You can also send them an invitation, and they can accept from their device.
