This book proposes that parents attemp to "sleep train" infants at particular ages, on the basis that babies are more receptive to training at particular stages of development. It is an EXCELLENT book for parents trying to decide when to train and I have recommended to many friends. HOWEVER it does not offer any information or advice on sleep training techniques.
I bought this boxed set as a gift and it was so reasonably priced I bought one for myself. I had not read Mr. Martin's work before, but had seen some of the Game of Thrones series. These four novels are fast paced,real page turners and very enjoyable for those who like fantasy fiction.
