"You don't have what it takes." That's the sentence that ran through Dr. Becky's head the night her baby threw up an entire bottle on her, minutes before she was due out the door. It's not a sentence parenting experts are "supposed to" have. Dr. Becky sits down with Emily Oster — economist, Brown University professor, founder of ParentData, and author of Expecting Better, Cribsheet, The Family Firm, and The Unexpected — to play a game: Science, or Vibes? They sort real claims parents hear all the time, on peanuts and allergy prevention, breastfeeding and attachment, sleep training, screen time, developmental milestones, and whether ChatGPT or Claude should be your parenting oracle at 11pm. Then they talk about the limits of expertise. Emily on teaching a business school class while her daughter was in the ER. Dr. Becky on the night her own psychology training couldn't talk her out of feeling like a failure. Their careers are built on having answers, and they describe the nights neither of them had one.
