There are no 7 manifestations that reflect smarter newborns, but newborns who perform better in foraging reflex, sucking reflex, grip reflex, and embracing reflex may be smarter. 1. Foraging reflex: Holding the baby in a semi-recumbent position, the index finger touches one cheek and the baby reflexively turns its head to that side. 2. Sucking reflex: when touching the newborn’s lips with the nipple or finger, the lips and tongue will suck and wriggle accordingly. 3. Grip reflex: lay the newborn on its back, the adult fingers from the ruler side of the newborn’s hand into its palm, the newborn will grasp the adult fingers, usually maintained for 3 months after the disappearance. 4. Embrace reflex: will grasp the newborn’s hands, so that its torso lifted off the bed, the newborn lifted after the head automatically down, the head does not have to lift the bed, and then quickly let go of the hand, the newborn will appear to straighten, and then embrace the action. The above performance can only be a preliminary judgment, is not the determining factor of intelligence, the child’s future still need to be cultivated and the correct guidance.
