Genetic mutations have been found in cord blood of babies exposed to second hand smoke.

–I don’t think that my children have any genetic mutations, but when I was pregnant with E my father-in-law insisted on smoking in front of me because he was in his hotel room, where we had come to visit him. I was so nauseous we had to leave. And as soon as I sat down in the car, I threw up. R told me to stay and “throw up on him next time.” I don’t think he meant that, but he was seriously angry that his father insisted on smoking when I told him it was making me feel ill.
