Shepherding a Child's Heart is a great book for parents with children of all ages. This book, by Tedd Tripp, is focused on teaching you, the parent, how to speak to the heart of your child. (Luke 6:45 "...out of the overflow of the heart the mouth speaks.") It provides ways of "shepherding your child's heart into the paths of life", God's way.
Highly recommended! We just started reading it not to long ago, and it is really helping us - our Pastor gave it to us when our newest baby was dedicated.
If you can't purchase the book, check with your local church or library to see if they have it. (If you want to purchase it, you can find it at CBD.com, Amazon.com, or if you are in Millersburg - possibly in The Carpenter's Shop ).
