What is the safest way to handle baby bottles?
Clean * Wash bottles, bottle caps and nipples in the dishwasher or hand wash, rinse and boil for 5 minutes or more just before refilling Refrigerate * Keep filled bottles of formula or breast milk in the refrigerator until just before feeding. * Refrigerate open containers of ready-to-feed or concentrated formula. Warming * Place bottles in hot (not boiling) water for 5 minutes. * Shake well and test milk temperature to make sure it’s not too hot before feeding. Microwave * Never microwave baby bottles. Microwaves heat unevenly resulting in “hot spots” that can scald the baby’s mouth and throat. source: http://msucares.com/health/food_safety/foodfaq56.
