Amsterdam infant stool scale is more useful for assessing children who have not been toilet trained than Bristo Stool Scale

A validated stool scale would help both parents and clinicians to describe and differentiate between physiological and pathologic stool appearance. The Bristol Stool Scale (BSS), which was developed at the University of Bristol, is a medical aid that classifies human stools into seven categories (Table 1) (1). According to the BSS, types 1 and 2 indicate constipation, types 3 to 5 may be considered as "within the range of normal defecation" (type 4 being really normal), and types 6 and 7 indicate diarrhoea.
