Nutrition plays an important role in the development of children. In particular, the nutritional needs of preschool children have special changes compared to the previous stage, because children grow both in size and intellectual development.

Supplementing nutrition too late or too early will affect development, and this is also one of the reasons for the increase in malnutrition in infants. If nutritional supplementation is too late, it will not meet the needs of the child and the child will often lack micronutrients, causing the child to grow slowly, be stunted and susceptible to infections because the child's immune system is too weak.
