Children and their temperament - who is more rebellious - first or second?

There's a huge difference between the first children and the second children, and that is stated by a recent scientific study by MlT Sloan school management in Boston.

What's the difference? Experts have observed the behavior of some 2 million children, brothers and sisters, and their second children have more rebellious behavior compared with older children. Parents ' age, social status, the distance between pregnancy, the problems that the family could face with justice, as well as the performance or problems they have had at school. Experts have also shown that if the second children are male and do not perform well in school, do not prefer school, are more inclined towards criminal behavior or problems with justice. Second children generally have about 2040% opportunities to have problematic behavior compared with the first children.

Why is that? According to researchers, this was due to the attention that parents would pay, as mothers and fathers in general will be more tolerant of their second children by gaining some experience from their first children. This results in second and more male children. We have read other studies that show that the first children generally have greater intelligent skills as well as greater economic stability in the future. / P SENSA
