This book is what it claims to be - a 'first course' on the psychology of 'child development'. I found it useful when doing both my GCSE and A level psychology studies ... now that was quite some time ago, so I'm sure there are newer books available. But the history of the subject will not change, and this book offers a sound foundation on psychological ideas, concepts, theories and studies concerning the main contributions to this field of knowledge throughout the 20th century.
If you are interested in how children learn, in child psychology, and the various perspectives that have been advanced concerning this area of study, then you'll probably find this book interesting.
It's well written, quite substantial, and serves as a useful introduction.
