The differences between only children and those raised with siblings tend to be positive ones. Ms. Falbo and Ms. Polit [researchers at the University of Texas] examined hundreds of studies in the 1980s and found that only children had demonstrably higher intelligence and achievement; only children have also been found to have more self-esteem. These findings, which have been confirmed repeatedly in recent years, hold true regardless of whether parents of only children stayed together and regardless of economic class.
With current statistics showing that one in five American families now have just one child, the topic is particularly relevant. "Call me selfish but, as the mother of one child, I enjoy more time, energy, and resources than I would if I had more children. And it is hard to imagine that this isn't better for my family as well as for me," Sadler wrote. What do you think? Is having an only child selfish on the part of the parents? Are only children at any sort of disadvantage compared to their peers with siblings?
