OBJECTIVE: To determine the average intake of growing-up milk energy, ratio of growing-up milk calories to the total calories per day, growing-up milk protein, and ratio of growing-up milk protein calories to the total protein calories per day and their relationship with overweight and obesity in children aged 2-3 years.  
METHOD: Cross-sectional study was conducted to determine the proportion of overweight and obesity, followed by case-control study to determine the relationship between growing-up milk consumption with overweight and obesity. Overweight and obese subjects were considered as the case group, while normal weight subjects were categorized as control group. Study was conducted in Jakarta since September to December 2018. Three days-food record analysis were performed.  
RESULT: A total of 292 subjects with 34 cases and 68 controls. The proportion of overweight and obesity in children aged 2-3 years was 12%. There were significant differences between case and control group in terms of growing-up milk energy intake [516.1 (0 to 1546.7) vs. 238.5 (0 to 1090.4) kcal/day, p<0.001], ratio of growing-up milk calories to total calories per day [41.1 (0 to 83.7) vs 20.8 (0 to 80.7)%, p<0.001], growing-up milk protein [18.9 (0 to 71.7) vs 8.6 (0 to 50.7) g/day, p<0.001], and ratio of growing-up milk protein calories to total protein calories [46.9 (0 to 89.5) vs. 19 (0 to 72.3)%, p<0.001]. 
CONCLUSION: Excessive consumption of growing-up milk had significant relationship with overweight and obesity in children aged 2-3 years.
