A bottle warmer is more useful for breastfeeding mothers. Some mothers have to go to work, and the milk drawn out by the breast pump needs to be heated before feeding the baby. The bottle warmer is indirectly heated with water, with a temperature close to room temperature, which is the temperature at which fresh milk comes out of the mother's body temperature. It is relatively uniform and can be poured at any time without the need to mix water, so it will not be hot or cold suddenly.
For mothers who feed milk powder, it is best to use a breast warmer to warm water and maintain a constant temperature of 30-40 degrees. Wait until the baby is about to drink milk before pouring in the formula and shaking it well. The bottle warmer can keep milk that cannot be finished at once warm, so as not to let the washed milk get cold. After warming, if you want to drink it immediately, because the leftover milk can only be warmed for 1-3 hours, otherwise the milk will spoil.
If the mother is in a hurry to go to work, she should "carry" the milk and refrigerate it, and give it to the baby when she is hungry. But before eating, it is necessary to heat breast milk to a temperature that the baby can accept. Conventional methods of warming milk are difficult to control the temperature, but a breast warmer can do it. Because the milk heater heats up the milk without water, and the temperature can be perfectly controlled without adjusting the water temperature, the warm milk is relatively uniform, avoiding sudden changes in temperature.
