One of the many reasons I remain childfree.
You cannot know the feeling of it until you do. You cannot really understand it until you do. It changes your world.
That's my main problem with it, it's super selfish to procreate. I don't feel I have the right to force new life (with all the pain and suffering that entails) onto this world for the sake of making me happy. I love my potential children too much to do that to them.
Give one reason to have children that doesn't include words like "I want".
