<p>This study examines whether greater women’s household bargaining power is associated with the improvement in children’s welfare in Ogun State, Nigeria. Using data from 320 farm households with a Logit regression model, the study revealed that 31.86 % of children under-five years of age were stunted, 32 % were underweight and 16.2 % were wasted. Children growing up healthy were 62 %, implying that one – third of under-five children in the study area still experience nutrition deficiency. About 3.33 % and 1.05 % children simultaneously experienced stunting and wasting together, which perhaps suggests a harsh deprivation environment. In addition, 63.33 % of women in the study area had low bargaining power implying that they lack control over important decisions in their households. Women who enjoy decision-making power in their households, particularly with large purchasing power, are associated with having children with better height-for-age, mass-for-age, and mass-for-height ratios. Women’s inequality as relates to intra-household bargaining power negatively affects children’s welfare and leads to chronic malnutrition. As a policy recommendation, it is therefore, important to enhance women’s status, which, with time will lead to more investment in their children’s education, health, and overall welfare.</p>
