First, if a second child is born, the children will take care of each other in their later lives. Whatever happens, they can discuss it. If the elderly at home are sick, they can take turns to take care of them to reduce the pressure of providing for the elderly. Brothers and sisters at home can help each other, and whoever has difficulties will help each other.
Second, if a second child is born, the family will prosper and continue to burn incense. Having a second child helps the daughter-in-law realize the wishes of the older generation.
Third, it is more conducive to the stability of marriage. Some families have only one child, and the probability of parents' divorce is higher than that of families with two or three children. If a child is allowed, the father can take it for a period of time and the mother can take it for a period of time. If there are two or three children, parents need to consider whether the children are willing to live separately, so I think the marriage is more stable.
Fourth, if you have a second child, the child has an extra playmate. Some children only play by themselves in childhood, but the two children are different. Two people can play together. Children's childhood is not lonely. It is really fun for two children to play together. The second-born brother can protect his sister, the second-born sister can be her best friend, and the second-born brother can take his younger brother to play and study together.
If we only consider family conditions, I think it is too one-sided. Earning money is to create good living conditions for children, but you don't want it to reduce the burden now. I think this is wrong. Of course, you can also listen to the boss's advice. I hope my answer is helpful to you.
