Everyone knows that babies are born immature in many ways and, above all, very dependent. Humans are what is called an "altricial species", which means that we are born very poorly developed, having to grow and mature abroad until we have the same characteristics as an adult.
This, however, does not mean that babies do not know how to do anything, since they are born with a series of reflexes that help them find and get food, avoid dangers, etc.
We have already spoken on other occasions of primary reflexes of babies, but now we can see it in the most graphic way possible: through a video.
Palmar or grip reflex
It is the reflection that occurs when we touch the palm of the baby's hand. The moment he notices something in his palm he closes his hand clutching tightly. This reflex helps them to take things and to look for them.
Babinski's reflection
Babinski's reflex is the one that occurs when the outer instep of the foot is rubbed against the baby. What happens is that the newborn stretches and turns the feet inwards.
It is a childhood reflex that must be lost between 12 and 24 months, as the nervous system develops.
Gear reflex
It is the one that appears when we take the baby with both arms and put it straight with the feet resting on a smooth surface. The baby will lift one leg and then the other, as if walking. As it is said, it could be a precursor movement of the march that will be made when it is 10-12 months (and onwards).
Moro or startle reflex
It is a reflex that produces babies a state of stiffness that helps them achieve balance or emit a signal for help.
It is achieved by taking the baby by the hands, making the gesture of lifting it by pulling them, but without actually doing so, and releasing the hands quickly. The baby will open your arms abruptly.
As a curiosity, this is the reflection that served, in a way, to the Spartans to filter the children who were going to be warriors or not. The Spartans took the babies and let them fall to the ground. Those with a more pronounced reflection of Moor that made them acquire such rigidity or posture that would help them survive were worthy of being warriors. Those who did not survive would not have been good warriors (according to them, of course).
Plantar reflex
It is like the grip on the palm of the hand. It occurs when we caress the sole of the baby's foot. The baby will flex the fingers towards the stimulus.
It's about a reflection that remains as the evolutionary residue of the days we walked on all fours (when we were monkeys).
Suction reflex
It is the reflection that It helps you get your food and calm down and comfort which consists, simply, in the ability to suck when it clings to the chest. There is also the search or turn reflex, which in the video is not specified but that the last baby runs perfectly (it is the one that helps to find the breast when it touches the cheek).
