These are prayers from a Russian prayer book for little ones (I've translated them):
Glory to the Father, and to the Son, and to the Holy Spirit, now and forever, and to the ages and ages. Amen.
Lord have mercy on my mother and father, my Godparents, and all my family.
Holy God, Holy Mighty, Holy Immortal, have mercy on us.
Holy Angel of God who protects me, pray to God for me.
Holy Saint (name of patron saint), pray to God for me.
And, of course, the Lord's Prayer.
