"If you want kids, just have the kids" sounds very irresponsible - a good way to create a lot of suffering. It is not a decision you can reverse. You should give it a lot more thought than to choosing your career, where/how you live, or to getting a pet. It is shocking that so often it is the opposite, and people 'yolo' into this decision.

If you are planning to involve your relatives, of course you need to first get their informed consent.
Having children is a decision and a choice. You are not forced into it. And it is a choice that must be made responsibly.
