"Here is our beautiful baby girl River Rose; 6lbs 6oz, 18 inches, and the greatest thing on the planet," the "Stronger" singer captioned this sweet shot of her baby girl napping in a red antique carriage.
The "American Idol" alum welcomed her first child, whose father is music manager Brandon Blackstock, on June 12, 2014.
Brandon has two children, Savannah and Seth, from a previous relationship. He and the singer tied the knot after a whirlwind romance on October 19, 2013.
