From the rite just published by the USCCB. Read it all here.
[For the unborn child]:
God, author of all life,bless, we pray, this unborn child; give constant protection and grant a healthy birth that is the sign of our rebirth one day into the eternal rejoicing of heaven.
[For the mother]:
Lord, who have brought to this woman the wondrous joy of motherhood, grant her comfort in all anxiety and make her determined to lead her child along the ways of salvation.
Lord of the ages,who have singled out this man to know the grace and pride of fatherhood, grant him courage in this new responsibility, and make him an example of justice and truth for this child.
[For the family]:
Lord, endow this family with sincere and enduring love as they prepare to welcome this child into their midst.
Lord, you have put into the hearts of all men and women of good will a great awe and wonder at the gift of new life; fill this (parish) community with faithfulness to the teachings of the Gospel and new resolve to share in the spiritual formation of this child in Christ our Savior, who lives and reigns for ever and ever.
