My best friend, a Mother of 6 year old twins & a 3 year old couldn't stop talking about how this book, HAVE A NEW KID BY FRIDAY, made her a new Mom and changed her kids behavior. I thought sure, but you don't have teenagers like me. She insisted that I could use some of the strategies and techniques too, so I picked up the book. Dr. Leman has such a firm, lighthearted way of describing his interventions even with teens. I especially liked his simple strategy of "Say it once, Turn your back, & walk away! Now I have more good times with my kids and our family has become so calm and peaceful. What a great attitude change I have seen in my 2 teens. If you want to have more positive relationships with your kids, I highly recommend this book!
