Sibling Differences Boil Down to Birth Order

Just as much as twins are very alike, sometimes siblings raised in the same home by the same parents can be complete opposites. Birth order has been used to explain and predict these personality differences, hobbies, grades in school, earning potential and much more. But can that be possible, and how can siblings be so different? First of all, birth order - firstborn, middle children, youngest - isn't the be-all, end-all that determines a child's later success in life, but birth order can help you deal with your kids more effectively. Before other children are born, firstborns have parents to themselves, and that often means there's more time to explain things to them and teach them. They're given greater responsibility, especially when other siblings come along, so they tend to grow up holding themselves to a high level of success.
