For parents who bottle feed their newborns, taking time to warm those bottles during the first few months can be time consuming. There is no need to warm the bottles; if given cold bottles from the very beginning, most babies will not object. We checked with our children's doctor, and he told us that there is no medical reason for giving babies warm bottles, that it was just a matter of preference. This certainly made a difference for us in terms of the ease of bottle feeding.
