Teaching the children the Catechisms

I have struggled with teaching the kids the catechisms. We use the Westminster Shorter Catechisms. I want them to learn them. I go over them with the kids some days. Katie and Jonathan are even picking them up. I didn't think they could because they are longer then the children's catechism. But as I was working with Jordyn, they started repeating them, too. I was visiting with a friend several days ago, and she had a book I would like to get and use. It is called Training Hearts, Teaching Minds: Family Devotions Based on the Shorter Catechisms. I really believe it is important for the family to know and understand the catechisms. I, however, am not consistent with teaching them. So my prayer for today is that I be more faithful in teaching my children the Shorter Catechisms. :)
