Newborn babies have tears, because newborn babies have normal lacrimal glands, which are the same as those of adults, and the lacrimal glands are able to secrete tears, which can cause tears to flow when they cry. It’s just that at birth, due to more water consumption and thinner skin, there is more water evaporation, and sometimes there may be fewer tears or even no tears when crying. However, if the baby has consumed enough milk and has enough water in his body, tears will appear when he cries. If there are fewer tears or very little urine, it is necessary to increase the amount of breastfeeding in time, or even intravenous infusion treatment, to prevent malnutrition caused by insufficient milk.
