Positive sucking reflex

Babies show sucking reflexes for a period of 0 to 3 months. Putting things in the baby's mouth will suck. After 6 weeks, the breathing, sucking, and swallowing reflexes are coordinated, and feeding will become more efficient. The chewing function of newborn babies is not complete, and breast milk or formula can only be taken by sucking action. Therefore, when objects such as cotton swabs or fingers are put into the baby's mouth, the baby will naturally suck. After 3 months it will begin to disappear slowly. Non-childhood sucking reflexes are more common in frontal lobe lesions and pseudobulbar paralysis.
