Abstract: A parent social network based on relationship of children, including of activities, needs, interests or combinations thereof, is described. The parent social network can identify at least two minors with a common activity, need, interest or combination thereof, identify an adult responsible for the identified minors; and propose to link the identified adults. The parent social network can also provide post and other data to a parent based on interests and activities of a child. The parent social network can also identify and subscribe the parent to relevant children related calendars. The parent social network can allow effective communication between relevant parents using messaging and other means.
