Introduction: Under nutrition remains one of the most common causes of morbidity and mortality among children globally. It causes about 3.5 million deaths, with 35% of the disease burden being in children under five years. Inadequate knowledge on breast feeding, inappropriate practices such as early and delayed introduction of complementary foods, low energy and nutrient density of food offered, feeding thin consistency feeds, small amounts and food restrictions due to cultural beliefs are often greater determinants of malnutrition than even the availability of food. Information on how to feed young children comes from family members, community practices and health workers. Since children are not able to look after themselves, they rely completely on people who are taking care of them, most often the mothers, so their source of nourishment is limited to what their mothers provide. Kitui County has a rapidly growing population, water scarcity, falling food production and low resilience to climate change. The combined effects lead to food insecurity, a major factor determining the children‟s nutritional status.
