When does the hug reflex disappear

summary

Hugging reflex usually occurs in children because the brain nervous system of the child is not mature, or because of nerve damage. Generally, the normal situation will disappear soon. If it remains like this, seek medical advice in time. Let's talk about when hugging reflex will disappear.

When does the hug reflex disappear

First, it usually disappears in two months. Some scholars believe that the grip reflex represents an evolutionary adaptation. Newborns with this ability are trying to "protect" themselves. In some cases, your baby can even support its own weight and pull down to the seat with help. In addition, for newborns with upright ability, when their feet touch the desktop to support upright, there will be automatic step action. Generally, the left foot is taken first, and then the right heel is taken. When the step is good, it is like walking, and some even take more than 10 steps, which makes parents marvel.

Second: for infants under 3-4 months old, when the mother or family members suddenly come to the child's side or make a noise, they will find that the child's arms are outstretched and stretched, and then flexion and adduction to the chest, showing a hug. We will think that the child has cramps. In fact, this is not a cramp, but a physiological phenomenon, which is called embrace reflex in medicine. If there is no such reflex in the neonatal period, it means that the child's brain nervous system is not mature, and there may be damage or pathological changes in the nervous system, intracranial hemorrhage or other intracranial diseases.

Third, the reflex was obvious 3 months after birth and disappeared 6 months later. If there is no such reflex in the neonatal period, it indicates brain injury. If one side of the upper limb lacks startle reflex, it indicates brachial plexus paralysis or clavicle fracture caused by birth injury or other reasons. The startle reflex can be delayed or disappeared when there is brain injury or acute disease. If it can still be caused after 4 months, attention should be paid; if it still appears after 9 months, it is the characteristic of chronic cerebral lesions.

matters needing attention

Hugging reflex may affect children's normal development, so this disease should be treated early, and can't be delayed for a long time. Therefore, parents should take their children to the hospital for treatment in time. Parents should pay attention to their children's physical condition and other reactions at any time, and don't let the sick children grow up healthily.
