There are baby graves year that date back as earlier as the 1950s, potentially even earlier: many are unmarked. The last infant grave marked in this cemetery is dated 2010; Warren issued an edict from prison banning sex in 2011, so few infants have been born since then (the few babies born each year are the product of institutionalized rape by ). There are also graves lacking any dates whatsoever. Some read simply, "Baby Keate," or "Baby Bateman," or "Baby Cooke," with holes where numeric date tiles might otherwise be placed.
