In order to estimate the effect of maternal diet during lactation on FA outcomes in the offspring (bold arrow), it is necessary to control for the effect of maternal diet during pregnancy. Without statistically controlling for this variable given its association to both the outcome (child FA) and the exposure (maternal diet during lactation), the resulting effect estimate would not reflect the true association of interest.
