After your baby is born, guilt can grow into a monster that sits on your shoulder and whispers into your ear, "Mirror, mirror on the wall—who's the guiltiest of them all?" The answer is working mothers. Every time you can't calm your screaming baby, the guilt monster will tell you that if you were a true mom, an at- home mom, you would know what to do. . . . Everytime something goes wrong at work, it will tell you that it's your fault for trying to be a "supermom."
