Prayer to the Theotokos for a Woman in Labor

Most Holy Virgin, Mother of our Lord Jesus Christ, Thou knowest the great distress of mothers at the birth of their children; have mercy on Thy servant and Thy daughter (name) and, through Thy intercession, may the Lord, by Thy mercy and grace, help her to bring forth a child without difficulty. O All‑merciful Theotokos, Thou needed no assistance when Thou bore the Son of God, yet may He, from the heights of heaven, give aid to His servant and to Thy daughter who needs it from the all‑good Lord.
May He grant her gracious divine strength at this time, and may the infant who is to be born receive promptly the purity and sincerity of heart and the light of understanding in Holy Baptism and thereafter a true conversion to the Creator and incorporation into the Church. To the Lord, through Thee, Mother of the Son of God, we turn and pray: be merciful to this mother when her time of labor comes, and obtain from the One born of Thee, Christ our God and Savior, that He strengthen her with His heavenly power. Amen.
