The Newborn reflexes are totally involuntary acts, that are disappearing with time. Specialists believe that these abilities are, in fact, an inheritance from our ancestors, which proves our origin, since they were necessary to survive in the hostile environment in which they lived.

These responses remind us of our animal origin and, by dint of repeating themselves for thousands of years, they have been recorded in our genetic code so that the newborn can use them, despite not having a fully developed brain.

These reflexes will allow you to perform surprising actions that, although they are not useful now, are used by specialists to assess your vitality and neurological health. Thus, before leaving the hospital, the neonatologist will perform the well-known Apgar test, which is based on the baby's reactions to any of these stimuli and their reflexes.

Thanks to its intellectual and emotional maturation, after months, it will begin to manifest voluntary reactions to interact with its environment, at the same time, these reflections are lost. However, do not try to check for yourself if you are still keeping them or have already lost them. The pediatrician is the specialist who knows how to assess them, in relation to their age, without harming the baby. Keep in mind that they can be an indication that something is wrong.

1. Galant's reflex. As the hand passes through the lower back and to one side, along the kidney area and parallel to the spine, the baby slightly arches the body to that side. This reflection will keep you up to the year.

2. Moro reflex. When the baby is lying on a soft surface, we hold him by the wrists and spread him a little. Then we let him fall backwards. The baby will open his arms and throw them forward as if to give a hug. Then cry. This same reaction also occurs when someone hits hard, when they make a sudden movement or when a bright light is turned on. It is believed to be a defensive reflex, which disappears by the fourth month of life.

3. Prehensile Reflex. It consists of the newborn's ability to hold tightly anything that touches the palm of his hand, such as his mother's finger or a rope. It is a remote reflex that allows the baby to hold on involuntarily. The contact that is established between the person who grabs him and himself favors affective bonding. Generally, it usually disappears after six months.

4. Search Reflection. It appears when you gently brush your cheek or the corner of your lips. The baby then turns its head in that direction in search of food. It usually disappears around four months.

5. Suction reflex. The baby sucks when something is put in his mouth. It can already be seen on ultrasound before birth, it intensifies around the third month and usually disappears around the sixth month when the act of sucking is voluntary.

6. Plantar grasp reflex. It appears when the baby feels a friction on the soles of his feet. Then, pick your fingers down, flexing them, as primates do to grip. Specifically, this is the reflection that lasts the longest, up to the year of life. Drag Reflection. By placing your baby on his tummy, he will try to move his legs to crawl forward. You can see him better if you put your thumbs under his feet. They will support you. This reflex disappears after three months of life.

7. RMarch effect. It is curious to see how the newborn makes the attempt to walk when held by the armpits and with one foot supported, lifts the opposite to try to take a step or several. It only lasts until the second month.
