It's important to watch out for iron deficiency after kids reaches 1 year of age. It can affect their physical, mental, and behavioral development, and also can lead to anemia.
To help prevent iron deficiency:
Limit your child's milk intake to 16-24 full ounces (480-720 milliliters) a day.
Increase iron-rich foods in your child's diet, like meat, poultry, fish, beans, and iron-fortified foods.
Continue serving iron-fortified cereal until your child is 18 to 24 months old.
Talk with your doctor if you're concerned that your child drinks a lot of cow's milk or isn't getting enough iron, or if you're thinking of giving your child a vitamin supplement.
