Weak sucking reflex in newborns needs to be closely monitored, mainly to see what causes it, and part of it can be recovered.
If it is caused by disease, the sucking response will recover after the disease is cured, but the sucking reflex will disappear as the child grows up, about 4~7 months after birth.
Preterm or low birth weight babies may also have poor sucking reflexes due to immature organ development, but the sucking reflex will gradually recover as the baby grows up.
The most common cause of poor sucking reflex is central nervous system disease caused by hypoxia and ischemia. Of course, infection is also a common cause, and the sucking reflex can be restored after the disease is controlled. When the disease is under control, the sucking reflex can be restored. When a newborn baby has a poor sucking reflex, it is important to actively search for the cause.
