It is the magnitude and quality of these factors that determine the personality of specific individuals at later stages of life. Study on child development involves the analysis of these factors and refers to a process that every child goes through which involves learning and mastering skills like walking, sitting, talking, and other childhood behaviors in given periods of time. These learning skills are the developmental milestones. Precisely, children develop skills in cognitive development, social and emotional development, fine motor development, speech and language development, and gross motor skill development. Actually, child development largely depends on brain development as this is the centre of all protocols and indeed brain content defines humanity. As such, we cannot talk of child development and in exclusion of brain development. This research paper will address the development of the brain and its influence on child's abilities to take another's perspective. Moreover, the paper will discuss how the developmental milestone shapes child's social functioning during late infancy and early childhood. Development of the Brain and Its Influence on Child's Abilities The human brain is fundamental in human life and indeed one cannot function without a brain. However, brain development does not start at birth but with the formation and closure of the neural tube, which is the earliest nervous tissue. The development takes a gradual course and its functionality effects with time (National Center for Infants, Toddlers, and Families, 2012). This is because the actual events that shape the brain during development are also store that information throughout life and as the child grows physically in early childhood, so does their brain development. In fact, at childbirth, the human brain is underdeveloped with most of its neurons not yet connected in networks. Hence, early brain development at this stage involves establishing and reinforcing these connections. The mode of connections among neurons highly depends on the growing child experiences on surrounding world and forms attachments to parents and the society. Psychologically, brain development in children relate to the genes and the environment of the growing child. While the inherited gene structures the brain, it is the healthy diet and external stimulation of the surroundings that connects the brain to reality thus influencing the child’s abilities. For a fact, brain development influences the child’s abilities to crawl, speak, eat, laugh, and walk. Therefore, the parental interactions and care accorded to the child are the most fundamental aspects of early childhood brain development that largely dictates the abilities of a child. The brain is able to develop due to the interactions and the care provided by the parents. Most significantly is that both parents are equally tasked to accord these brain development drivers. In addition, the five senses of vision, hearing, smell, taste, and touch enable the development of unconnected brain structure. Actually, the scent of the mother's skin define smell, the father's voice define hearing, drinking the mother’s milk define taste, seeing a face or brightly colored toy define vision, and the feel of a caressing hand define touch (Brotherson, 2005). From these connotations, we can qualify the fact that early childhood is the most significant stage in brain development.
