We are beyond thrilled to announce the birth of our daughter, Lyla Maria Schwarzenegger Pratt. We couldn’t be happier. Both mom and baby are doing great. We are extremely blessed. Love Katherine and Chris Psalm 126:3 The LORD has done great things for us, and we are filled with joy. Psalm 127:3-4 Behold, children are a heritage from the Lord, the fruit of the womb a reward. Like arrows in the hand of a warrior are the children of one's youth. Blessed is the man who fills his quiver with them! He shall not be put to shame when he speaks with his enemies in the gate.
