All I know is that I can never let my older brother see this article! But to be honest this makes a lot of sense lol
A new study from the University of Edinburgh in Scotland has found thatolder children are smarter than their siblings. If you have younger siblings, then you know that parents tend to get a little more laid back with each child. While a first-born usually receives tons of attention and monitoring, and younger siblings enjoy more freedom, the increased parental attention has myriad benefits for developing brains.
"First borns score higher than their siblings in IQ testsas early as age one, the study has found," the University of Edinburgh reported. "Although all children received the same levels of emotional support, first-born children received more support with tasks that developed thinking skills."
