Were any babies BORN in Nazi concentration camps?

This would include the offspring of women who came to a camp pregnant and were healthy enough to work or of women who became pregnant as a result of sexual congress in the camps.

I have been watching a lot of movies about the concentration camps (including the 6 part PBS Auschwitz series) and this question entered my head. I know of babies and young children being killed in the camps (through various means), but was not sure if any babies had actually been born in the camps.

I ask this question with awareness that the SS may have not allowed these infants to live for long, but I wondered if they allowed them to be born at all.

I also ask with the full understanding that it certainly could have happened and we might never know. I am interested in learning if there are any facts about situations wherein it is a certainty that a baby was born in one of the camps.
