The temperature of the milk warmer should be set at 40-45°C. This will ensure that the warmed milk will not be too cold and stimulate the gastrointestinal tract, but will not be too hot and damage the baby’s digestive tract mucosa or cause the loss of nutrients in the milk. If the temperature is too high, it will destroy these nutrients and lead to nutrient loss. If your baby drinks overheated milk, it will cause damage to the mucous membrane of the gastrointestinal tract; if the temperature is below 40°C, the milk may be too cold to stimulate your baby’s gastrointestinal tract, leading to indigestion and diarrhea. In addition, the use of a milk warmer also requires timely drinking. The nutrients in the milk will also be destroyed by prolonged insulation, and leaving the food at a low temperature for a long time will cause the milk to deteriorate.
