On this week’s episode: Dan talks with Emily Oster, professor at Brown University and data-driven parenting author. She also writes ParentData, an evidence-based newsletter that has been a vital resource for many parents navigating the pandemic. Emily and Dan talk about how families should act now that more families are falling into the ‘mixed-vaxxed’ category and what to expect for the upcoming spring and summer.  Dan, Jamilah, and Elizabeth also tackle a question from a listener who has fallen out of love with professional sports. Now his little boys are starting soccer. Should he jump back into the sports fandom or is it okay to stay out of the fray? (Overtime: We chatted with soccer legend Abby Wambach last year about raising competitive athletes, especially when the parents aren’t sporty. Check it out.)  In Slate Plus: The hosts share the soundtracks to their parenting. Slate Plus members get a bonus segment on MADAF each week, and no ads. Sign up now to listen and support our work.
