Hi. I am expecting a baby in Feburary. My husband will be taking care of her during the day when I return to work. I have decided to pump milk and attempt to breast feed. He doesn't want to rely on the skin test to see if the bottle is at the correct temperature. Is there any bottle warmers that regulate the temperature of the bottle perfectly? If not what ones to ya'll like and what method would you use to determine of the bottle is the perfect temp?
