Second thought rpreetipj, you are quite right about the assessment tool for infants of Voita. It is depending on reflex which come at a certian stage in infancy, like paraschute reflex (opening arms and legs when a baby is moved fast prone downwards) These reflexes you can look up and then you will have a gross idea about when they should occur and how reflexes like standing on toes and 'walking' occur at a very early stage (UPTO 4 MONTHS of age).
