Further revisions to the checklists can include simplifying the words and sentences and providing relevant pictures to aid understanding. If the checklists are to be used for screening, standardization of how the checklists are to be completed and how children at risk of developmental delays can be identified on the checklists need to be provided. Parents' awareness of the importance of evaluating their child's development at 9 months, 18 months, and particularly at 2.5 years, needs to be raised. Developmental screening for children at these critical ages can be made mandatory. An electronic version of the health booklet is likely to facilitate implementation of developmental screening in the health care system.
