There are nearly 100 baby boxes in Germany. Poland and the Czech Republic each have more than 40 while Italy, Lithuania, Russia and Slovakia have about 10 each. There are two in Switzerland, one in Belgium and one being planned in the Netherlands.
In the last decade, hundreds of babies have been abandoned this way; it's estimated one or two infants are typically left at each location every year, though exact figures aren't available.
"They are a bad message for society," said Maria Herczog, a Hungarian child psychologist on the U.N. committee. "These boxes violate children's rights and also the rights of parents to get help from the state to raise their families," she said.
"Instead of providing help and addressing some of the social problems and poverty behind these situations, we're telling people they can just leave their baby and run away."
