Wow, I never thought that I would dare to enter into this conversation...but, after reading the last dozen postings, I thought, what the heck!
I come from a French-Canadian strict Roman Catholic background. My parents each have 7+ siblings, my parents had 5 children. I have 11 nieces and nephews. My DH and I (married for 13 years next June) do not have children and have made the decision at this time to remain childless (who knows, if the hormones kick in in our 40's, adoption might be an option).
I see my couple and single friends with and without kids, and I am just not convinced that having children is a guaranteed path to happiness. Some of them are overjoyed, some of them are miserable. Some of them would love to be in my position (happily married, no kids) and others can't quite understand whether our neurons are firing: "You just don't know what you are missing", "Of course you will have kids, you'll see".
My parents are relieved that we are not having children (less for them to worry about, they have enough grandkids as it is) which may sound harsh but I know it is true. So there is no pressure from that side. My DH's parents have pretty well given up on us...
There is alot of societal pressure on us...probably less now than in our 20's as most of our friends have given up and kind of see us as amusing (in a nice way), we're unique. I think the most important thing to do is take stock in your life, and decide individually what is right for you, for whatever reason. I don't like to think I am selfish to not have kids as there are SOME people who do many things, such as having kids, for reasons beyond the love of a child and could be considered selfish behaviour. Deciding to have or not have kids CAN be a selfish act, but recognizing whether you want to commit to a lifetime of being a parent before having kids and deciding that that component of life is not something you are particularily interested in, is not a selfish thing to do. It's good planning and judgement.
I would love to use the whole 'planet overpopulation' excuse, but I can't really buy that. Yes, in India and China, there are issues. But here in North America, we are going to have serious labour shortages with the Baby Boomers getting older and us Generation Xers having less than our 2.1 kids. We will not have the health human resources to manage these aging Boomers. So I can't really get on that soapbox.
I am a very happy, happily-married women, I have a dog to lather my love upon, and have a job within the health care field that I feel is meaningful to many people. I am a good person, and I love my family. Life is good! Would having a baby make it better? I don't know. Who really could predict it? It could be a disaster or the most wonderful experience in my life! Is it a risk to either take the chance or not take the chance? Absolutely. There are risks to either decision.
Ah, my two cents...
