Results: The results show that age and stimulation that mothers given effect Mental Development Index (MDI) and Psychomotor Development Index (PDI) on malnourished children. The equation for PDI was Y = 43.849 + 9.322 children's age -7.942 mother's age + 0.009 mother' age * the amount of stimulation often given. The equation for MDI was Y = 91.344 + 25.972 children's age -11.217 mother's age + 0.198 mother' age * the amount of stimulation often given. For MDI was 25.7% and for PDI was 9.3% by children's age after controlling mother's age and stimulation that often given. In order to catch the optimal growth and development, the main focus to improve went should only focusing on body growth but also mental and motor development as well.
