When To Have A Baby Shower If Due In December? Baby showers are happy gatherings when friends and relatives celebrate the newest member of the family. This custom, which dates back to ancient civilizations, is known by several names in different countries, but they all honor the arrival of new life. It is undeniable that baby showers have been a family tradition for ages, regardless of whether they are conducted before the baby is born, shortly after, or just as a "sprinkle," as is customary for any kid following the first-born. Prior to organizing a meal, putting out invites, and deciding on a date, you must first decide who will host the celebration.
