I’m guilty!  I’ve fondly identified myself as an “Angel Mom” even though what I meant was “Saint Mom”, but “Saint Mom” sounds awkward, it needs explaining – there is a certain connotation to the word “Saint”.   Not everyone will instinctually know what you are referring to, but maybe we should take the time to help others understand.  This is a great article that explains the difference, called Why Our Babies Aren’t Angels…And Why It Matters.
