Answer:
a. Vitamin C and iron
Step-by-step explanation:
As of the sixth month, this milk begins to be insufficient to meet the nutritional demands of growth, and it is time to start incorporating food that complements its contribution. For this, the consultant clarifies that the situation of babies who only breastfeed is different, from those who receive formula milk.
In the complementary feeding of children who receive exclusively the breast, it is necessary to incorporate meats, liver, eggs and fruits early, to avoid nutritional deficiencies (iron, zinc, proteins and some vitamins).
On the contrary, children who receive infant formulas or a combination of formula and breast in more than two thirds of the contribution as a formula, complementary feeding is less critical because the formulas are already added with vitamins and minerals. This is the reason why many pediatricians indicate iron and vitamin supplements (mainly vitamin C) from the sixth month on children who receive exclusive breast.
