Infancy
After around nine months inside the mother’s womb a child is born. During the infant stage the individual is extremely dependant, the adult would have to feed, nurture and look after the infant. Infancy occurs from birth to around two or three years old. Although every individual goes through the developments, they occur at different rates.
The physical developments that occur in the first two years are rather dramatic. The infant’s weight will double from birth to five months, triples by twelve months and quadruples by the age of twenty four months. During this stage the individuals length does not change as rapidly as the infant’s length at birth is already 75% of what it will be at two years old. The head grows the fastest followed by the rest of the body downwards. The brain triples in weight and size by the age of three. During the first year the child masters a number of gross motor skills. One to two months old, the individual will hold up his head, four months may involve rolling from side to side. Between seven and nine months the child may sit up without assistance begin crawling and pulling himself up to standing. Around eleven to twelve months the infant will attempt walking.
The social and emotional developments of infants are broken down in months. During the first few months infants learn to identify to their own needs and feelings and how to respond to them. They begin to develop a trust and a bond begins between the individual and its family. The social and emotional development increases as the individual becomes more aware of the people and things
