Previous CDC studies have shown that nearly everyone in the U.S. is exposed regularly to low levels of perchlorate. People are exposed through eating food, and drinking milk and water that contain perchlorate. Trace levels of perchlorate have been found in both breast milk and infant formula.revious CDC studies have shown that nearly everyone in the U.S. is exposed regularly to low levels of perchlorate.

When you add solid foods to your babyâs diet, continue breastfeeding until at least 12 months. You can continue to breastfeed after 12 months if you and your baby desire. Check with your childâs doctor about vitamin D and iron supplements during the first year.
At about 6 months, most babies can start to eat solid foods. This complements breast milk or formula. Try to be patient as your baby experiments and learns new eating skills like chewing and using cups and utensils. For more information about feeding, see the topics Breast-Feeding, Bottle-Feeding, and Weaning. Follow your doctor's advice on when and what to feed your baby.
