If a woman converts to Judaism while pregnant, will her child be a Jew once born?
There is also a dispute over whether the fetus is considered a part of its mother or not, and therefore, whether the child was born Jewish, or is considered to have converted with its mother.
I recently saw a case where Rabbi Dr. Barry Fruendel, the RCA's representitive to the Israeli rabbinute for coordinating procedures and standards for conversion, converted a pregnant woman, her husband and their first child, and held that the child yet to be born would be born Jewish. I was a bit surprised. I remember that his predecessor at Kesher Israel, in Washington, D.C., Rabbi Rod Glogower, shlita, would not convert a woman married to a Jewish man until they determined that she was not pregnant. The traditional procedure was to have the couple separate for 3 months. However, doctors convinced Rabbi Glogower that there was a 24-hour pregnancy test that was 100% reliable, and he permitted that test in lieu of the couple separating.
