Breast milk contains immune factors that help to protect infants from disease. There is substantial variation across societies in the rate of infant mortality due to disease during the second and third years of life. How would you expect such mortality rates (i.e., the risk of infant death due to disease) to affect weaning conflict involving a healthy infant? Justify your response using evolutionary reasoning.
