The "infant Jesus" refers to Jesus Christ during his early years, particularly his birth and infancy. According to the Christian tradition, he was born in Bethlehem to Mary and Joseph. His birth is celebrated on Christmas, and it is believed that he was born in a stable, where he was laid in a manger. The story of the infant Jesus includes visits from shepherds and the Magi, who brought gifts of gold, frankincense, and myrrh. This period is significant in Christianity, symbolizing the beginning of Jesus' life and his role as the Savior in the New Testament.
