Four-month-old infants greatly rely on the palm to determine how they will grip an object, 8-month-olds are more likely to use a pincer as a guide.
Infants usually grow faster than children of any other age. Along with physical development, their fine motor development also remains at pace. Infants usually grasp the objects put in their hands in many different ways as they grow older. Reflexive grasp, crude palmar grasp, and pincer grasp are the stages of a baby learning to hold things as he grows up.
Newborn babies automatically grasp anything put in their hand, this is called palmar reflexive grasp. By the age of four months they start using their palm to hold things, this is called a crude palmar grasp. Going through the scissors grasp, the baby will finally develop their pincer grasp.
Pincer grasp allows babies to hold things with the top of their thumb and index finger. They also start to use their fingers to point at things they like. This is around 8-month-old or when they are around to complete the first year of their birth.
