I’ve heard it said before that having your own and seeing someone elses’ children is not the same, the whole “you cannot understand until you have your own yada yada”.
As a parent myself, I would never recommend anyone to have kids who really don’t want it. It’s okay to never want to see a child again, if that is was you want. I love being a parent but that is my experience and my life.

If you are fine as it is now, then there is not need to change it. What should matter to you is that you are happy, not someone else.
