ABSTRACT Background: Detection of growth and development in children needs to be carried out early, so that immediate treatment can be taken before the child reaches the school-age stage. This detection can be carried out using the Development Pre-Screening Questionnaire, however, many mothers with toddlers are found to not carrying out such monitoring or detection. Methods: This study employed the correlation analytic with a cross sectional approach. The sample was 67 people, selected through probability sampling. The data were analyzed using Spearman Rank test. Results: The results showed that the average value of mothers‟ knowledge was 75.52, median 80, minimum value 55, maximum value 85, and standard deviation 10.41. The average toddlers‟ visit was 3 times with 1 time visit was the least and 4 times visit was the most (p value = 0.000; CI = 0.082). Conclusion: There is a significant and strong positive correlation between knowledge of mothers and toddler visits for developmental monitoring using Developmental Pre-Screening Questionnaire.
