Hello @phyllis.boger phyllis.boger,
Welcome to the LastPass community!
If you want to start up sharing with your daughter, there are two options if she is part of your family account you can share using a share folder which is the best option since if you make any changes to any of the items you are going to share the changes will be shown to your daughter immediately or the other option is the one time share or share an item which is a process where you share an item only once but no changes will be shown you will need to stop sharing and re-share. You can find more here: Manage shared folders in LastPass and Share an item in LastPass.
Kind Regards,
Alejandra
