Warm breastmilk needs to be heated to about 40 degrees, between 37 and 42 degrees. Breastmilk has a temperature of 36 to 37 degrees in the human breast, but there is a cooling process after warming the breastmilk, so breastmilk is usually heated to about 40 degrees. It is not advisable to heat breastmilk to a temperature too high, the temperature should not exceed 42 degrees, the temperature is too high will lead to the destruction of the nutrients in breastmilk, reduce the nutrition of milk, and the baby’s skin mucous membrane is fragile, the temperature is too high is also prone to cause the baby’s oral mucous membrane and digestive mucous membrane is scalded. However, the temperature of warm breastmilk should not be too low, not less than 36 degrees, otherwise the baby in the consumption of too cold breastmilk will lead to indigestion, diarrhea, bloating, vomiting and other symptoms.
