I was 7 when I thought about having children for the first time, and I didn't want to lol. Things changed A LOT ofc, but no I still don't see myself having children. It's something that changes, though. At times, I would like to, but 95% of the times I don't. I'll say that when I had a bf it felt "more doable", so I guess that being single might have its role in this kind of decision as well.
On the other hand, logically speaking, I'd never have a child. First of all, I am myself undecided on my future, and a lot of things can happen, so like idek where in the world I'll end up, then economic issues, and I guess myself being rather selfish, meaning that I'd rather live a more comfortable economic life only by myself, rather than also taking care of a child.
