In Jewish tradition, placing a small stone on a grave is a quiet act of remembrance and a gesture of respect. It speaks of a visit made, a love that still lingers, and honors the one who is lost. The stone remains—solid, steadfast—like memory itself, and is a symbol of something everlasting. These mothers’ stories are their stones. Though their children never lived in this world, they existed and will never be forgotten. Every year, more than 20,000 pregnancies, or 1 out of every 175, are lost at 20 weeks or later in the U.S. despite research showing that 1 in 4 are potentially preventable.
