Someone told me that in their family they have the minhag (practice) that at least once a day everyone is called by their full Jewish name.
For example, a girl is Chana Ester Riva. People call her Chana but once a day her mother makes sure to call her Chana Ester Riva for her to have a long life.
Do other Jews have this minhag?
It is for the same reason (long life)?
What sources exist regarding this minhag?
