Should my baby be talking by now?''Why hasn't he started feeding himself yet?' Anxious parents the world over ask themselves these same questions. A recent survey by the Social Issues Research Centre revealed that three-quarters of parents wanted more guidance on whether their babies' cognitive skills were above or below average. In response to this, leading psychologist Dr Dorothy Einon, has devised a test that will enable you to address these and many other developmental concerns. Simple, observational tests, conducted at home, will help you to monitor your baby's physical, cognitive and social development and compare him to the average baby of his age. You can chart yout baby's growth rate, test his senses and mobility, find out what he can understand, remember and recognise, as well as learn how he perceives the world. Dr Einon provides fascinating insight into the mind of a baby and gently reminds parents that while some babies do develop at an exceptional rate, all babies are different and those with lower scores have plenty of time to catch up with their peers.
