How is the newborn crying? The newborn baby's lacrimal gland and accessory lacrimal gland may not be fully developed, so some of them will not produce tears for the time being or can secrete few tears, so most newborns cry without tears or have a little tears when they cry, but some newborns may have early lacrimal gland development, and there will be tears when they cry at birth. This is also a normal phenomenon, and parents need not worry too much.
Most babies begin to secrete tears gradually after one month of birth, so tears will gradually increase when they cry. If there are no tears when the baby cries one and a half months after birth, go to the hospital to check whether there is obstruction or dehydration of nasolacrimal duct that causes the baby to cry without tears, and carry out relevant treatment.
After the newborn is born, all the organs of the body are not fully developed, and the growth and development speed of each organ and tissue is different. Generally speaking, more important organs and tissues will be developed first or relatively fully.
In particular, the development of the nervous system is generally earlier than the heart and lungs of other organs. Function and other important organs, the growth and development are relatively perfect, and the lacrimal gland of newborns is also in a process of gradual development.
In the neonatal period, because the lacrimal gland is not developed enough, the tear marks may not be obvious when crying. Later, with the passage of time, the lacrimal gland will gradually develop and the tears will gradually increase. When crying in the newborn, you can have tears or you can have fewer tears.
