When talking about a new addition to the family, we often use the term "newborn infant." However, there are several other synonyms that can be used to describe a baby that has just been born. Some of these include "neonate," "new arrival," "recently born," "newbie," "fresh arrival," "infant," and "nursling." Each of these terms describes a baby that has just entered the world, with "neonate" being a more technical term used in the medical field. Whether you are talking about a "new arrival" or a "nursling," all of these synonyms convey the excitement and joy associated with the birth of a new baby.
