Oh boy…
Wondering why your preschooler is beating up on you and his playmates? Look no further than his big brother, say researchers who reckon that having an older brother makes younger siblings more aggressive.
Research by the University of California, Davis indicated that while a particularly aggressive older sister may potentially wreak the same havoc on her younger siblings, having an older brother was a big factor in predicting a child’s level of aggression in adolescence.
In general, having a younger sister made older kids less aggressive, while children with younger brothers demonstrated fairly stable levels of aggression over time. Mom and dad are in the mix too: parental hostility was also key when it came to kids displaying aggressive tendencies. Economic pressure also played a part in straining parent-child relationships because it tended to increase parental hostility.
That’s not all big brother might be doing to the kids either – previous research has indicated that boys may have a five-point IQ advantage over his sisters by adolescence. Having an older brother can also affect how tall younger siblings grow: statistics show that by 10 years old children with several older brothers are shorter than average. Experts have theorized that the boy effect may be caused by boys being more demanding on parental resources.
