The effectiveness of dietary changes in a lactating client can be best determined by evaluating the weight gain of the infant. This approach is grounded in the principle that the nutritional needs of the breastfeeding infant are directly influenced by the mother’s diet. If the mother makes dietary changes that positively affect the quality or quantity of breast milk, it should be reflected in the growth patterns and weight gain of her infant. Consistent weight gain indicates that the infant is receiving adequate nutrition, which is essential for their development during the first few months of life.

While monitoring the client’s energy levels, assessing the client’s food diary, and checking the frequency of breastfeeding can provide ancillary information about the mother’s well-being and dietary habits, they are less direct measures of the effectiveness of the dietary changes on the infant’s nutrition. For instance, the mother could report increased energy levels or maintain a detailed food diary, but if the weight gain of the infant is lacking, this would indicate that the dietary changes might not be sufficient or effective in providing the necessary nutrients for the infant’s growth. Therefore, the infant's weight gain serves as the most concrete indicator of whether the dietary changes are effectively supporting lactation.
