Detailed explanation-1: -Babies a few months old are unable to organize movements to grab an object voluntarily. The palmar reflex probably serves to create a basic motor pattern that lays the foundation for obtaining this voluntary ability. Furthermore, this reflection creates interaction and bonds between the infant and the adult.
Detailed explanation-2: -This reflex is an important sign of your baby’s nervous system development and function. 1 Plus, it helps your newborn get some much-needed skin-to-skin contact with you and loved ones.
Detailed explanation-3: -2.2. The palmar grasp reflex and the plantar grasp reflex can be elicited in all infants during the first 3 and 6 months of age, respectively. Thereafter they decrease along with the intensity of the responses, usually disappearing by 6 and 12 months of age, respectively [6, 7, 25–27].
Detailed explanation-4: -Sucking reflex (sucks when area around mouth is touched) Startle reflex (pulling arms and legs in after hearing loud noise) Step reflex (stepping motions when sole of foot touches hard surface)
