Using the 1993 South Africa Integrated Household Survey, this paper studies the effect that mother's education through the knowledge channel has on children's health using height for age Z-scores as health measure. Under a two-stage least square methodology we find that an increase in 4 years on mother's education (approximately 1 standard deviation) will lead to an increase of 0.6 standard deviations on her child's height for age Z-score. We also find, as the medical literature suggests, support for the hypothesis that mother's education is more important for children older than 24 months of age.
