JJ Heller writes lullabies with her husband Dave and sings them for children, their parents, and the children inside the parents. Since 2017, the Hellers have released a new song on Spotify the first Friday of every month. One of those songs, “Hand to Hold,” grew into a picture book by the same title, released a couple of weeks ago. In this episode, I speak with JJ and Dave about bedtime liturgies and the work of giving language to parents’ deepest hopes for their children.
