"It indeed wonderful to see the father leads the Rosary while the mother and children harmoniously respond."
This is the tradition in our household. It has become such an integral part of our daily routine that my sons ask when we're going to pray the rosary next. My (one-year-old) daughter makes the sign of the cross and babbles along during the responses.
It is amazing and humbling to witness how much praying together can truly bring a family together.
