A new study by the Erasmus Medical Center in The Netherlands found that women who work more than 25 hours a week have babies that weigh on average 5-7 ounces less than moms who don't.
And if their jobs include extended periods of being on their feet, the new moms can expect infants with heads an average of 1 cm smaller around.
But don't quit your job just yet. According to the new study, all this work doesn't seem to cause any further complications to the health of the baby, such as premature birth.
Though if you do have to stand for hours at a time, it might be a good idea to take a "pregnant pause" every once in a while.
