(LONDON GUARDIAN) The United Nations is increasingly concerned at the spread in Europe of “baby boxes” where infants can be secretly abandoned by parents, warning that the practice “contravenes the right of the child to be known and cared for by his or her parents”, the Guardian has learned.

The UN Committee on the Rights of the Child, which reports on how well governments respect and protect children‘s human rights, is alarmed at the prevalence of the hatches – usually outside a hospital – which allow unwanted newborns to be left in boxes with an alarm or bell to summon a carer.

The committee, a group of 18 international human rights experts based in Geneva, says that while “foundling wheels” and baby hatches had disappeared from Europe in the last century, almost 200 have been installed across the continent in the past decade in nations as diverse as Germany, Austria, Switzerland, Poland, Czech Republic and Latvia. Since 2000, more than 400 children have been abandoned in the hatches, with faith groups and right-wing politicians spearheading the revival in the controversial practice.
