Shirley, Over the years I have known dozens of adults who were raised by a JW parent/parents who never got baptized or never attended once they were on their own. They are not part of any congregation but still identify themselves somewhat as JWs. (Kind of like nonpracticing Catholics)
Because they don't associate no JC action is taken. Even though they don't practice the religion they still hold at least some of the beliefs so that they would not want to assign another religion to their children especially as infants.
