Small blisters on the forehead of newborns are called sweat blisters. Sweat blisters occur when the room temperature is too high or the newborn’s blanket is too thick, making it difficult for the child’s heat to escape from the body. If a newborn baby has sweat rash, the way to deal with it is: first, to reduce the temperature of the environment or the thickness of the blanket; second, you can use sterilized gauze or a warm towel to wipe it slightly harder. Note that it is important to prevent infection in this area, because the capillaries under the skin of newborns are fragile and may lead to infections in other parts of the body due to infection.
