Career-minded mothers-to-be have one more reason to cut back on working overtime during pregnancy: their babies' size. New research published in Occupational and Environmental Medicine
found that women who worked over 40 hours a week were more likely to give birth to smaller babies than women who worked 25 hours a week or less. Additionally, women whose jobs required them to be on their feet all day also had smaller babies than those who did more sedentary work. This disparity, according to WebMD
, was discernible from the third trimester on.
