Is it karma to have a daughter and no son all your life?

It is normal. What is this karma? I know two families, one of which gave birth to three sons. The three sons have grown up and are worthless, and the youngest son is still gnawing at the old. One gave birth to three daughters, all famous college students, and now she is buying a house for her parents. Most of the families that raise girls around me are excellent, study well, obey and love each other. This is the happiest.
