Last year I read this GREAT book called "Boundaries with Kids." I wish I had read it before I started youth ministry because it makes the shaping process that kids need to go through so clear. It provides good ways to put boundaries in place for your kids no matter what age they are. I felt like I had learned some of those things along the way by trial and error (because nobody else was teaching this stuff) and other things I saw that I had totally missed (many "aha!" moments). Now that we have Abby I need to go back and read it and work on applying it to the stage she is at right now.
I want to read one book on parenting each year, but I also want to review this book each year because what it contains is so simple and powerful, yet easy to forget over time. I would HIGHLY recommend this book to ANY parent, no matter how long (or little) you have been parenting or grandparenting. You can take this and apply it to any stage of development in your kids' lives. You will probably have a few "aha!" moments along the way and be encouraged to keep pressing on as you train up your children in the way that they should go so that when they are old they will not depart from it!
