Yes, the Nazis did KILL babies during World War Two
Yes, the Nazis killed babies during World War Two. This was part of their systematic extermination of Jews, Roma, and other groups they considered to be "undesirable." Babies were killed in gas chambers, by shooting, and by other means. The Nazis also carried out a program of forced sterilization on women who they considered to be "racially inferior." The exact number of babies killed by the Nazis is unknown, but it is estimated to be in the hundreds of thousands.
The Nazi genocide was a horrific event in human history. It is important to remember and learn from this atrocity so that it never happens again.

Others were sent to a hospital barracks to wait out the rest of their pregnancy in squalid conditions. Sister Klara, a midwife who had been sent to the camp for murdering a child, oversaw the barracks with a woman named Sister Pfani. They were in charge of declaring babies born in the ward stillborn, then drowning them in buckets, often in front of the mothers who had just given birth. Sister Klaras role did not include assisting with deliveries.
