My brother and his wife are expecting their first child (sometime in November). While I can't imagine my brother being a parent or being responsible for another living, breathing creature, I am happy that they have decided to go the route of the breeders. I do not want to have children, neither does the man. I don't dislike children, per se, but I do feel awkward around the especially tiny ones and the ones where you have to monitor their bodily functions (aka what goes in and what comes out). I have never changed a diaper and would be perfectly happy if I made it through life without ever having to do so. It isn't that I think I would be incapable of parenthood, I just don't carry the desire to procreate. Personally, I believe that I have had to raise enough "children" in my 24 years of life - I have had many friends whom I had to take care of, clean up after and make sure they didn't burn the house down.
Breeders keep telling me that it's different when the kids are yours - they are less annoying and it is a pleasure to take care of them. I don't doubt that the bond creates a different experience, but I do believe that I could establish a bond with someone else's kid and then send it home when the fun wears off. Perhaps I am selfish, but I don't see a need for everyone to have kids. I know a number of DINCs who are happy and content with their lives (DINC = dual income, no children). The man and I have pets and I feel that they are close enough to offspring.
Taking care of pets (aka Jack) has also shown me that I am not cut out for reproduction. I love Jack and wouldn't trade him in for anything. He is a fast learner and will soon be able to take care of himself, for the most part. At ten weeks of age he is in control of his bodily functions and I only have to supply him with a food source, attention and litter box maintenance. In return he idolizes me and hisses at the roommates, which makes me happy. A human child would take much more effort and I wouldn't be able to spray it with a water bottle if it were naughty. Plus, I don't think children land on their feet if they fall from high places.
In other words, I would much prefer to be the cool aunt who spoils the hell out of her neices/nephews and then hands their sugar-laden, sticky selves back over to their parents.
