I've been invited to a First Communion dinner party. Should I bring a gift?
Yes. An invitation to such an event is typically reserved for only very close family and friends, and a gift would be traditional.
Aside from those attending the First Communion celebration, who should purchase a gift for a First Communion?
Generally just close family members would give a gift to the communicant. Other friends might send a note of congratulations, but a gift is not traditional.
