Sixty children were examined for their nutritional status and their mother or carer was interviewed. There were no under-nourished children were found based on the antropometric examination among samples, where 91.5% of the children had a normal weight and 8.5% were over-weight. Despite the good nutritional status of the children, 60% of the mother or carer had a poor level of knowledge regarding nutrition for children. The proportion of children who were given complementary foods before and after the age of 6 months was similar (49.1% and 50.9% respectively). There were higher proportion of children from a lower income family (55%) as compared to the children who were from higher income family (45%). Among the samples, the proportion of children who were taken care by their mother were almost similar to those who were taken care by the other family members (50,85% and 49.15% respectively).
