Teratogens could have contributed to Evans development causing his low birth weight, biological development can be affected causing inadequately developed organs such as immature lungs. Poverty, sanitation, water supply, housing, food supply and general hygiene all posed risks and childhood illness were prevalent. Anna and Evan were entitled to Vitamins, the national vitamin welfare in 1942 ensured nursing mothers and children under five received free orange juice, vitamins and cod liver oil and the national Milk scheme ensured they received free milk ( Wartime women giving birth, 2013). This will given Evan required nutrients to assist with Physical development. According to Eriksons theory of trust vs mistrust ( simply psychology, 2013) Anna supported Evans Psychosocial developments as she was responsive towards him in a positive way, this will have developed his sense of trust. This could be a response to nurture however, Bowlby (Simply psychology, 2013) suggests that a baby is born it has an innate attachment with its mother, which would suggest nature. Infants are born with innate motor reflexes enabling them to suck and grasp, this will then support physical movement and coordination. Evans cognitive developments will support him with his first communications such as crying and other baby noises. Piagets theory suggests that from Birth -2 infants go through a sensorimotor intelligence stage in which they are processing new things, (Development through the lifespan, 2007)
Evan remained shy of his father as an attachment had not developed, when David was at home he was often drunk, tired and aggressive, this made Evan feel anxious around his father. Anna would interact with Evan playing and reading for many hours. This encouraged Evans physical development and intellectual development, he was soon putting small sentences together and playing with toys and began walking when he was 15 months old.
