This book derives from almost five decades of research, beginning at first with ethological observation of free-living chimpanzee mothers and infants undertaken in 1971 in cooperation with Jane Goodall, [5] [6] [7] [8] and then extending to more elaborate research with human mothers and infants. The existence of regular 'regression periods' and their correlation with stages of cognitive development are well documented in the literature of ethology [9] and child psychology, [10] [11] [12] [13] and the findings underlying the book have been replicated in different countries and cultures by several independent research groups. [13] [14] [15] [16] Further corroboration comes from independent lines of investigation into periodicity of early childhood illness, [17] Het ouderschap kan een onzekere tijd zijn. Van de spanning tijdens de zwangerschap, tot het herstel na de bevalling of voor de eerste/tweede/derde keer een kindje opvoeden. Met alles wat wij doen, willen wij ouders helpen om echt zelfverzekerder in hun schoenen staan. Door hen onbevooroordeelde informatie te bieden, kunnen zij weloverwogen keuzes maken voor hunzelf en hun baby! Parenting can be an uncertain time. From the excitement during pregnancy, to recovery after giving birth and/or raising a child for the first/second/third time.

What exactly is your baby going through?According to the book, babies go through 10 predictable 'leaps' in their cognitive development during the first 20 months of life. These correspond to successive developments in the growing brain, as manifested in the child's ability to perceive and then to control a new kind of perceptions at a higher level of the perceptual hierarchy.
