If you have decided to bottle feed your baby, cool formula won’t hurt him. Most parents want to warm formula to body temperature. Don’t heat bottles in a microwave oven. The bottle may feel cool on the outside but will still have hot spots inside that could burn your baby’s tender mouth.
Heat the bottle in a pan of warm water that has been removed from the burner, or hold the bottle under hot tap water for a minute. Always shake the bottle well to mix the formula. Test the temperature by sprinkling some formula on the back of your hand. If it feels lukewarm, it’s OK for him to drink.
