The first 3 chapters made me feel like a terrible parent, saying that things like time-outs and counting to three don't help. There were many tips that helped me and that I continue to do with my children (like special one-on-one time). But other things just weren't working for us. While the logic behind most of the tips is sound, in reality not everything works for every child or parent. Because counting to 3 does work on my boys... I only have to say "1" before they know I mean business.
The overall suggestion is to be a loving, patient, parent who takes time with their child to listen and play with them. And to remember that even small children have their own ideas and thoughts of what is important to them, though it may not seem important to an adult. So try to think from the child's perspective and treat your child and their thoughts & feelings with respect.

I recommend this for any parent, just try not to take the criticism too personally. This book would be especially good for those who are not yet/soon to be and/or new parents before getting set in a certain parenting pattern, positive or negative.
