A parent tells a nurse that her toddler drinks a quart of milk a day and has a poor appetite for solid foods. The nurse should explain that the toddler is at risk for which of the following disorders?

A. Toddlers who consume excessive amounts of cow’s milk (more than 24–32 ounces per day) can fill up on milk and not consume iron-rich solid foods, leading to iron deficiency anemia. Milk is low in iron, and excessive intake can also interfere with iron absorption. B. Rickets is caused by a vitamin D deficiency, which leads to poor bone mineralization. While milk is a source of vitamin D if fortified, the toddler’s high milk intake actually provides vitamin D, so rickets is less likely in this context. C. Type 1 diabetes is autoimmune, and type 2 is rare in toddlers. Excessive milk intake alone does not directly cause diabetes. D. While excessive caloric intake can contribute to weight gain, this scenario primarily poses a risk of nutrient deficiency (iron) rather than obesity, especially if the toddler is not overeating overall calories from solids.
