Edited to add: I found this prayer and the beautiful holy card on Facebook.
My grandmother had a great devotion to the Holy Innocents because she lost 7 of her 14 children, most before birth, due to a blood type difference w/ my grandfather. I think of her (and my aunts and uncles in heaven) whenever I hear about the Holy Innocents. Now I will think of these poor, innocent children as well.
Holy Innocents, you died before you were old enough to know what life means, pray for all children who die young that God may gather them into His loving arms.
Holy Innocents, you were killed because one man was filled with hatred, pray for those who hate that God may touch their hearts and fill them with love.
Holy Innocents, you experienced a violent death, pray for all who are affected by violence that they may find peace and love.
Holy Innocents, your parents grieved for you with deep and lasting sorrow, pray for all parents who have lost young children that God may wrap a warm blanket of comfort around them.
Holy Innocents, those around you certainly felt helpless to prevent your deaths, pray for all who feel helpless in their circumstances that they may cling to God for courage and hope.
Holy Innocents, you who are now in Heaven, pray for all of us that one day we may join you there to bask in God's love forever.
