As your baby transitions to solid foods around 6 months, introducing iron-rich foods becomes important for preventing deficiency. Research suggests focusing on foods like meat (excellent source), beans, fortified cereals, and other iron-rich options. Iron deficiency is the most common nutrient shortage in toddlers worldwide, and it's usually caused by not enough iron-rich food in the diet. The good news: it's entirely preventable with thoughtful food choices. If you're feeding your toddler formula, most formulas are already fortified with iron, which helps protect them. If you're considering a plant-based or vegan diet for your child, that's doable but requires careful planning to ensure they get enough iron, B12, zinc, and calcium—ideally with guidance from a doctor or dietitian. Focus on variety and consistency, and ask your pediatrician if you're unsure whether your toddler's diet provides enough iron.
