Innate reflexes are the automatic and involuntary responses that the newborn performs in the presence of a certain stimulus. The reflex response generally implies a movement, as in the case we are talking about today, the babinski reflex in the baby, also known as plantar extensor reflex.
Babinski's reflex consists in the movement of the big toe upwards, towards the instep, and the other fingers open in a fan when the baby's sole is rubbed hard.
The baby's primary reflexes tend to disappear after different periods, in the case of Babinski's reflex it is normal in children up to two years, although even before, even before reaching twelve months, it can disappear. It is around 18 months when this reflex usually inhibited by the upper centers.
That is to say, it usually disappears after the crawling and crawling process of the baby, crawling with the tip of the feet helping each other for movement, and when starting to walk. If the child walks on tiptoe it could be because he has skipped this stage and Babinski's reflection It has not disappeared (although we do not have to worry, this is probably not the cause and it is the pediatrician who has to confirm it).
When Babinski's reflex occurs in a child older than two years or in an adult, it is often a sign of a nervous system or brain disorder (amyotrophic lateral sclerosis, brain or spinal cord injury or tumor, meningitis, multiple sclerosis, stroke ...).
In short, we can prove that our baby has the Babinski reflex, since birth, massaging or pressing the sole of the foot, although like any temporary reflex, it will disappear when the child grows.
