Today is the feast of Our Lady of the Rosary, which commemorates the Battle of Lepanto. (For more on the Battle of Lepanto, see this fine piece by Fr. George Rutler.)
And don't forget that October is the month of the Rosary. Do you pray the family Rosary? If not, October is a great month to start, and if you haven't started yet, today would be the perfect day.
And remember, if five decades is too much for your little ones, consider beginning with just one decade. Also, consider using images of the Rosary to help you meditate on the mysteries as you pray your Our Father's, Hail Mary's, and Glory Be's. It was with this in mind that I created the Sacred Art Series Rosary Flip Book. Hopefully it will be as helpful for your family as it has been for mine.
Our Lady of the Rosary, pray for us!
