To achieve this reflex movement, lay your baby flat on his or her back. The head should turn to one side with one arm and leg extended in the direction the baby's head is turned and the opposite arm and leg are in a flexed position. There really isn't any known survival benefit for this reflex. This reflex is in an attempt to avoid pain. Babies receive a whole slew of tests as newborns and, if you will notice when the heel of the foot is pricked for a blood test, the leg and foot will jerk backwards and the opposite leg and foot push forward.
Babies are incredibly resilient and smart.
So, remember, when you are noticing that yawn, or your baby is grasping your finger it is all in the name of survival. Each one plays a great part in your baby's survival in this world.
