Methods The clinical trial results of the revised version of “Bailey infant and child scale of China” compiled by Hunan Medical University were analyzed. Results There were no significant differences in the MDI and PDI between different sexes, and the incidence rates of male and female under MDI79 were 20.86% and 13.6% respectively. The incidence rates of male and female under PDI79 were respectively 20.32% and 1 5 .1 6%. There were significant differences between MDI and PDI in 301 cases of different age groups. Among the 477 normal children, the unacceptable items were mainly cognitive ability, fine motor and gross motor dysfunction. 54 cases had developmental delay and criticality The etiology of the state was perinatal factors, and the second was social psychology. Conclusion The BSID test can detect children with poor development and mental retardation early. We should seize the opportunity to carry out early education and early intervention so that the potential of the brain can be fully exploited
