Home Environment
we assume that children from the same family grow up in the same home environment. However, a second theory of sibling differences indicates that this may not always be true. For example, in the case of two brothers, when Paul was born, he was an only child and got lots of attention from his parents. By the time James was born eight years later,the house was full of noisy children. His parents’ marriage was starting to fall apart. They divorced when James was four. His mother began working full-time and did not have much time for him. James rarely saw his father. All of these factors point to childhood environments that were very different for the two boys
