Because conditions varied wildly over time and across the different camps (political prisoner camps, forced labor camps, ghettos, etc.), I will concentrate on Auschwitz since there is rather a lot of material available about this harrowing subject.
Warning: this is not pleasant reading
Before the autumn of 1944, when systematic gassing of Jewish inmates was halted, all Jewish babies were killed upon birth, generally together with the mothers who were guilty of the “crime” of arriving or falling pregnant in Auschwitz. If the pregnancy was discovered before the birth, the women were killed too. This led to the drama of improvised abortions and concealed births followed by infanticide, either by the hands of the mothers or by the physicians, nurses or midwives among the inmates that were assisting them in their labor. The most famous of these doctors was Gisella Perl, a Jewish-Romanian gynecologist who wrote I was a doctor in Auschwitz in which she describes how she performed many abortions to save the mothers’ lives.
After October 1944, Jewish babies were not automatically killed, but this didn’t increase their chances of survival significantly, as no accommodation was made for the welfare of mother and child, and the women were expected to continue with the excruciatingly hard work and subsist on literal starvation diets. There are only eight recorded births of Jewish babies in Auschwitz. There is no record of any surviving.
The Family Camps:
There were two “family camps” at Auschwitz where certain groups were allowed to live on as best they could on starvation rations and racked by diseases caused by overcrowding and unsanitary conditions. The inmates in these “family camps” were not subjected to wholesale gassing of children, the sick and the elderly upon arrival as the regular transports were and families were allowed to stay together.
The “Gypsy” camp was established before it was finally decided that these people were all to be exterminated too. There were sporadic gassings, though. It housed Sinti and Roma families from February 1943 to August 1944. Occasionally, groups of inmates were sent to other camps for forced labor. On August 1944, almost all the remaining inmates were killed. More than 370 children were born in this camp, though it is unclear whether any survived.
The Theresienstadt family camp was in operation from September 1943 to May 1944 and was part of the whole Theresienstadt propaganda effort to “prove” to the outside world that Jews were not being killed after deportation. It housed families deported from the Theresienstadt ghetto in Bohemia who were forced to write letters about how good they had it at Auschwitz and that the families were staying together. Pregnant women were allowed to give birth. However, after six months the camp was liquidated to make room for new transports from Theresienstadt, and these inmates in turn were all killed in July 194
Non-Jewish and Non-”Gypsy” Women:
Most of these women were Polish and Soviet “political” prisoners, though there were some German inmates (Jehovah’s Witnesses, women convicted of crimes, prostitutes, etc) as well as a smattering of “political” prisoners from other countries. Policies were more erratic here. At first, these women were killed upon arrival if they were found to be pregnant. If they fell pregnant after entering Auschwitz, they generally resorted to secret abortions much in the same way as did the Jewish women. Starting from 1943, women were allowed to give birth, but many babies were subsequently killed, sometimes immediately, sometimes later, depending, it seems, on the whims of the SS. Generally, the women were forced to kill their own babies, or this was done by the medical staff who were inmates themselves. However, some blond and blue-eyed babies were taken away to the Potulice concentration camp or similar places that acted as transit camps for Polish children who were deemed to look “Aryan” enough to be subsequently adopted by German couples. In September of 1943, the first baby was officially registered as a camp inmate and received the distinctive Auschwitz tattoo with its inmate number. At liberation there were 156 children of less than three years still alive in Auschwitz, but it is not known how many (if any) of these were actually born there (a number of children were sent to Auschwitz in the wake of the Warsaw uprising of autumn 1944). The living conditions were such that a baby had very little chance of survival.
