Primitive reflexes in babies
This is one of the primitive reflexes that all newborn infants have, but are lost as they grow past six months old. Many of these reflexes are to protect the baby and carry a survival advantage, but some have no benefit.
In the swimming reflex, placing a baby face down in water will cause them to kick and paddle. The aim is to buy enough time until someone can come and help. It carries risks, however, since the baby may swallow large quantities of water or aspirate it into their lungs.
Another example is the palmar grasp, where placing an object --- such as finger or toy --- into baby's palm will cause a strong grip.
