In developing countries, the level of growth and development of children in these countries is much lower than that of the international reference population due to inadequate or unbalanced dietary intake and frequent episodes of diarrhea and other diseases. In this paper, the impact of these factors on children’s growth and development were qualitatively analyzed. A total of 70 children from 5 to 18 months in Bangladesh were followed up for 14 months.
