Get the parent's and a neighbor's number. Baby's Bottle Older babies can drink a bottle from the refrigerator. Test the temperature of the milk by putting several drops of milk on your wrist. If stored breast milk is used, ask the mother how to handle it. Be careful warming hard plastic or glass bottles in the microwave.
Hot spots can occur in microwaved bottles and cause burns in the baby's mouth.
To heat in the microwave, remove the cap and nipple. Let stand for a minute. Replace nipple, shake and test on your wrist as suggested above. Milk, formula or food that is left out of the refrigerator for 2 or more hours should be discarded. A bottle should not be left in the crib with an older child.
