They are a rich resource of balanced, sensitive and non-judgemental advice to help parents and professionals looking after children. The central subject is the mental and emotional development of children and their parents. And the style is intelligent and friendly. Each book is divided into very easily digestible sections, with excellent (and often very funny) case studies scattered liberally throughout and a really detailed contents page for those "where did I see that bit about"moments. The books form a cohesive and continuous guide to almost everything I have ever wondered about bringing up my children. I learnt a lot. And a friend, mother of her first two-year-old, could not wait to get her hands on these when I described them. They are now going into our bathroom "reference library" for family and visitors to peruse and digest.
