To be sure, only children experienced some things differently from those with sisters and brothers. Many feel more pressure to succeed. In the absence of brothers and sisters, only children also tend to look more exclusively to their parents as role models.

In India, 10-year-old Saviraj Sankpal founded a support group for the tiny minority of only children. Among other things, the group does volunteer work to counter the myth that they are not responsible. “People think we’re treated too kindly and ruined,” says Sankpal, a computer engineering student. “But I’d like to remind them how lonely it can get.”

Most only children, however, say they wish for sisters or brothers only when it comes to caring for aging, unhealthy parents. Britain’s David Emerson, coauthor of the book The Only Child, says that such a person bears a terrible burden in having to make all the decisions alone. Emerson knows from experience: After his father died, he chose to move his elderly mother from their family home, where she was vulnerable(易受攻击的) to house breakers, to a new one with more security. “The move was quite hard on her, and she might feel that I pushed her into it,” he says. “After all, I am left with that responsibility.”

In the future, more and more only children will likely face similar choices. With working mothers increasingly the rule, many families are finding they simply don’t have the time, money or energy to have more than one child. As only children become common, perhaps the world will realize that the charge made against them is unjust.
