I really hate people who use sex for reproductive purposes. I always think that we have children because we get along well with the other half and love him very much, so I am willing to have children for him. It's not about having a boy or a girl. Including the witness of our love, and should not be a tool to carry on the family line. My mother is also a great career, not a fertility tool, so I hate people discussing the sex of the fetus.
Xin Wei and Ryan already have a very lovely daughter, so it may be a good thing for them to have a son. Anyway, many people are looking forward to having a son and a daughter, so that life is more complete, because you have experienced the feeling of having a son and a daughter. After all, raising two children of different sexes is actually a different experience. Although they are all fathers, they feel really different.
But I think it should be natural to have a son or a daughter, and you can't have anything for the sake of having something. We should put the baby's health first, and everything else is second. I believe Xin Wei and her husband feel the same way, because they may not care about these things. They are pregnant with a second child in the hope of having more children, regardless of gender.
