Newborn crying without tears, until they are a few weeks

Toddlers are not yet developed some zhelezy



Although it is known that they often cry, newborn children are not capable of producing real tears. This is because their lacrimal channels are not yet fully developed, even after birth. Therefore, they are only the basal tears - liquid enough to sustain their eyes moist and healthy. This period of "crocodile tears" lasts from three to 12 weeks after birth, when the lacrimal canals child finally formed.

In addition to the lack of developed lacrimal gland in newborns is also no active salivary glands. But that's OK, because children eat liquid food, as long as they do not appear teeth. Sometimes, in the first three months of their life, these glands begin to work, but the child does not know how to swallow saliva. This is the reason why babies drool.
