Neonatal clinic. A paediatrician examining the reflexes of a newborn baby in a neonatal clinic. Here she is testing for the stepping reflex. Although unable to support its own weight, a baby will attempt to walk if the soles of its feet touch a solid surface. Present from birth, this reflex disappears at about six weeks of age. Photographed at a clinic at Chelyabinsk, Russia.
