Our family enjoys family devotional time around the breakfast table. Troy leads us through scripture memory (which Number 3 loves!) and a section from this book.
The key to all learning is asking the right questions. Leading our children through the shorter catechism asks them the right questions and gives them a solid Biblical answer. If you ask the wrong questions, you may come up with great answers, but you will be heading in the wrong direction. Even if they don't understand it right now, the right questions can been asked and the foundation laid.
...unless your five yr. old repeats the first question of the shorter catechism like this:
"What is man's pwimawy porpoise?"
See, wrong question leads to wrong answers!
