This seven-pound baby needs 17.5 ounces per day. 17.5 ounces per day divided by 6-8 feedings equals 2-3 ounces per feeding. A normal newborn without feeding problems could be burped halfway through the feeding and again at the end. If burping needs to be at intervals, it should be done by ounces or half ounces, not minutes. Microwaving is not recommended as a method of warming due to the uneven heating of the formula. If used, the formula should be shaken after warming and the temperature then checked with a drop on the wrist. The recommended method of warming is to place the bottle in a pan of hot water to warm, and then check the temperature on the wrist before feeding.
