UNLOCKED from our Patreon page, it\u2019s the Meaningful Differences Book Club! Voted on by our patrons in 2020, we discussed "Meaningful Differences" by Hart and Risley. \xa0And here it is: 2+ hours all about this classic, and sometimes controversial, book documenting Betty Hart and Todd Risley's longitudinal study exploring the home lives of 42 families to try to determine why some children develop more robust language than others. \xa0If you ever wondered where the 30 million word gap comes from, you've found it. \xa0
