* Gassing: Babies were gassed to death in gas chambers along with other prisoners. This was a common practice in extermination camps like Auschwitz-Birkenau and Sobibor.
* Shooting: Babies were also killed by shooting, either by firing squads or by individual SS officers.
* Injection: Babies were sometimes given lethal injections, such as phenol, to kill them.
* Bludgeoning: Babies were sometimes killed by being bludgeoned or struck in the head with blunt objects.
* Starvation: Babies were also killed by starvation. They were often deprived of food and water for several days until they died.
* Hypothermia: Babies were exposed to freezing temperatures and died due to hypothermia.
These methods were used in an attempt to kill babies quickly and efficiently, without regard to their suffering. The murder of babies in concentration camps was a horrific crime against humanity and serves as a reminder of the depths of depravity that humans are capable of.
