Also, if you have appreciated the morning and evening prayers and liturgies we put together for this time, you may enjoy Every Moment Holy (https://www.everymomentholy.com/) a fantastic book full of liturgies you can use with your kids, or on your own. Below are links to a few of their free, downloadable liturgies. You'll also see a link to a blog at the bottom, "Various Prayers for A Time of Suffering."
