how do I include family members to an existing contact?

[Guest]

I want to add a contacts family members to that contacts file. The reason is
so I can add their children's birthdays to my calender under the parents name
instead of listing each individual child as a separate contact. Any help
would be appreciated. Thanks

You can add a spouse and a child, BUT, you can only add a birthday or
anniversary for the MAIN person on that contact...
