Happy Dance! After a very long time (longer than I would like to admit), I finally spent the day creating my own Prayer Journal. This link will take you to a download site and you can print it for your own use. In the future, you'll be able to find it under the new page, Daily Prayers for Children.
I didn't want a dated calendar because I want to be able to use it EVERY month. So I made a simple table with 1-31 for days of the month and added daily prayers for my kids and my husband. I added a third column for "others", but left some blank so you could add your own.
I hope you'll check it out and let me know what you think.
