I completely agree with you that family happiness does not mean that one will be happy if one has more children. No, even if you have only one or two children and you have given them a good life and good education. And if happiness is always visible on the faces of your family, then no one is happier than your family. Therefore, it would be wrong to say that only a big family is always happy, a small family can also be happy. You have expressed your thoughts very well. May you get success.
