Firstly the difficult aspects. This book is 500 pages long, and at times seems padded out. As it is so long it may daunt some parents before even opening it, and I have a mental picture of a parent telling their child to go away as they are busy reading about how to be a better parent! I also found Nicky Gumbel's opening page off putting as he writes about what wonderful parents the writers are!
These objections laid aside, this is a very helpful book, and I would recommend it to parents, and anyone who seeks to relate to others. It either could be read straight through, as I did, or you could simply read a chapter or 2 on your particular issues or area. The cartoons also make it an amusing read, enjoy!
