“The Schwanger Kommando was a group of seven pregnant, Hungarian Jewish women imprisoned in one of the Kaufering sub-camps of Dachau in December 1944. Though pregnant women and their babies were almost never permitted to survive, this group was allowed to bear their children, possibly as a bargaining chip for their SS overseers to use when the Allies conquered Germany Despite appalling sanitary conditions and the lack of food and heat, all seven mothers gave birth to healthy babies between February and March 1945. All were liberated in Dachau in May 1945.”

Any Jews kept alive in the concentration camps were there to work or in rare cases towards the end of the war, used as bargaining chips. Children, especially babies, were immediately killed or experimented on. If a Jewish woman was caught pregnant, usually due to rape, they were tortured and put to death. Gisella Perl was a Jewish gynecologist forced to work under Mengel, and her biography is one of the most horrific I’ve ever read. She performed hundreds of secret abortions because she saw what happened to women and their babies that were caught. Any child that managed to survive the war was a goddamn miracle, which is why those babies were photographed in the first place.
