On that special day when we welcome our child into the world and "officially" become a mother, something else very special transpires in the delivery room (aside from hubby's pale green skin slowly returning to a normal color).
Our child receives his or her very own guardian angel.
According to St. Thomas Aquinas and other early Church Fathers, up until the time of birth an unborn child is protected by its mother's guardian angel. When the baby finally becomes physically detached from mom (yes!), he or she is assigned their own angel who will accompany them throughout their life.
I can just imagine the conversation as the exchange takes place: "He's all yours now. Watch out, he's a kicker."
