Why do more researchers think that birth-order influences on child development have been emphasized too strongly?

Birth-order influences on child development.

Explanation:

It is said that birth-order influences on child development due to different reasons. The first child is the one who obeys rules, is self-critical and is the role model for his/her brothers or sisters. On the contrary, the middle child is more rebellious, popular with friends and as he/she is in the middle, he/she does not spend as much time as he/she can with his/her parents. And the youngest child is the one who is spoiled, is more creative, likes to show off and most of the times, his/her brothers or sisters feel jealous of him/her. This is scientifically proved and if you have more than one child, you will see all these differences among brothers and sisters. But the most appropriate is that parents make all their children feel the same as important so they do not grow up with traumas and have a normal life in the future.
