I'd rather not, but the future is never certain, is it? It's not something I like to talk about very much, but basically, I feel children would overtake my identity and people would just think of me as their mother rather than as my own individual due to the way motherhood is depicted in media. That incentive people have to continue their legacy... I don't have it myself and I really do not understand it. A child would never be the continuation of myself, because they're a different person. And to call them a part of me is an injustice. I am not a part of my parents. I'd be insulted if anyone suggested I was. And I have no desire to fill this world with spawn for the sake of the instincts of reproduction which humans still have in powerful quantities.
I'd rather live on for a long time than have a child. And if I could exchange my ability to bear children for that, I'd definitely go for it. Besides, a child's a crapshoot. You never know how the thing's going to turn out. Even if you raise it in all the right ways, a person's never a guarantee. Also, all of the money and the thought of having to spend my me time taking care of it... it isn't appealing.
We'll see what happens though. But if I do decide to create a thing, it will ONLY be one. I am not going to spread myself thin with any more. And I will hope that twins do NOT happen.
And a bit of a later addition: Not against adopting at all. If I ever decided to do this though, I'd probably take in an older child. Like a young teenager. That way, most of the annoying parts of it not being fully sentient would be out of the way. And yes, I know teenagers are a hassle. But I'd much rather deal with one of those older kids that nobody really wants than a small child. I don't like young child and do not understand them.
