Most of young infant's conscious memories appear to be short lived, although their implicit memory of perceptual motor actions can be substantial.

Explanation:

A young infant aged two months can only remember things for a few days at a time. As the infant grows, they will start remembering things for longer periods of time. A nine-month-old can remember for approximately 1.5 months. At the age of 2, is when a young child can start retaining their memories. There are some instances where people state that they can remember things from infanthood, but this is not a common occurrence.  

Perceptual motor actions are when an infant is retaining sensory information. There are numerous sensory inputs that an infant will learn throughout the years as they grow. One of the first things an infant learns through this action is kicking, waving their arms, and raising their heads by themselves.
