Happy feast day of Saint Anthony of Padua. Here's a great prayer for pregnant mothers and their unborn babies:
Glorious St. Anthony, you were blessed to hold the Infant Jesus in your arms. I come to you now on behalf of (mention name) who pleads for the health and safety of the child that God has graced her to conceive.
St. Anthony, guard this life God has created, and the mother God has chosen for this child. Let your gentle hand, like that of a skilled physician, aid in her delivery so that this baby will know good health and lasting happiness.
May her child be favored with the grace of holy baptism, and grow to love our Lord Jesus Christ above all else in this world. Amen.
