If you squeeze your newborn’s nipples, it can cause the following negative consequences: first of all, it can cause pain. When squeezing a newborn’s nipples, the nerves above the nipples are more sensitive, which can cause pain and lead to violent crying. Secondly, it can lead to inflammation of the local skin of the nipple. This can lead to localized skin infections, causing redness and swelling of the nipple, because the skin can be broken after squeezing the nipple. Then it can cause sepsis. Because the immunity of newborns is very fragile, the function of immune cells is not mature, when squeezing the nipple will cause the spread of infection, if the bacteria invade the blood will cause sepsis, which is also a very common hazard, so it is wrong to squeeze the nipple of a newborn.
