Why do people prefer having more than one kidWhen ever people have only one child I have seen many elders advising them to plan for one more kid. Some people advice saying that having one more child will give a company for the first child so that the first child will not feel lonely and they can play together. I have also heard others giving advises saying going for a second child is good because if something happens to first child or they lose the first child they will still have another child to depend on.
What is the reason people go for more kids? I know its every parents personal choice and the thinking differs but what could be the reason?
