The first child is a son. What does the doctor mean by increasing assets?

What the doctor said to you is as ambiguous as a fortune teller's fortune telling.

It is true that on the day when the child is born, both men and women will think that what the doctor said to you is right.

Try to guess without hiding, and take good care of yourself. Generally speaking, it is always a good thing to "increase your assets" as the doctor told you.

I hope my answer will make you feel something.
