How To Reply These Kinda Questions

I have a son and a DD. Now people ask whether I don't plan for the 3rd one.
I said my factory is closed.

My bro has 2 DDs, and SIL is often attacked with Qns like when is she gonna give birth to a son. She says, next time.

My sister has a DD and son, and if anyone asks about having a same gender sibling to her kids, she says they have cousins and they are more than siblings.

These one line answer are more than enough to shut these questions. Just that you need to be firm in answering.
