Week 4 Discussion – Juan G

Is there any research on the language development of an only child vs a child with multiple siblings?

As I am reading about how children demonstrate cooperation, not aggression, with children with whom they meet repeatedly, I wonder if it is the same case for siblings. I remember fighting with my siblings all the time even when I knew we would play again; I observe similar behavior with my nephews when they play with their siblings compared to when they play with friends. I wonder if this has to do with the age difference.
