OSV Kids The Rosary helps children learn to pray and love this traditional Catholic prayer. When we pray the Rosary, we remember important moments in the life of Jesus and Mary, which are known as the Mysteries of the Rosary. With a Rosary book of their own, children can take the first steps in developing a life of prayer and devotion to the Blessed Mother, who always leads us to Jesus. Perfect for families, schools, and parishes, this beautifully illustrated booklet includes instructions and all the prayers of the Rosary, along with age-appropriate meditations and questions for reflection.
