The most crucial pieces of information to include on a baby shower invitation: date, time, place (with directions from several points), who the shower is for, RSVP information (with a respond-by date), the sex of the baby (if known), and where the mother-to-be is registered for gifts. If there is special information pertaining to this particular shower, by all means, include that also.
