Interesting, I can't say I've encountered many girls my age (I'm 18, by the way) who actually want kids right now. I know my mother had me when she was 18, but that was accidental, and a former girlfriend of mine now has a baby boy, but that too wasn't on purpose, although I don't think either of them would change what happened for the world. Yet I've never encountered anybody my age who wants kids so young.
I mean, biologically speaking, late teens and early twenties are the prime time for women to have children, and so I can understand how that would be a time when some girls may turn their attention towards having a baby of their own. It's a perfectly natural desire. My girlfriend, who's 19, recently confided in me that she's been having such feelings lately, although we both agree that it's better to wait until we can provide a stable environment for any kids to grow up in (that, and the fact my own mother has threatened to castrate me if I dare make her a grandmother before she's at least 45). Of course, in today's society, we've been conditioned to consider teenage pregnancies as this big, bad, scary thing that should be avoided at all costs. We have messages of safe sex and birth control pounded into us 24/7. Society tells us that no teenager can possibly bring up a child in this world, and that to try otherwise is irresponsible and could hurt the child. These messages aren't necessarily bad, in fact, the first two do serve very positive functions. Many teenagers underestimate the risks of STIs and teenage pregnancies, or do stupid stuff without the proper precautions (because, let's face it, horny people are not reasonable people). Many of these teens aren't prepared for the challenges and stress a child would bring. By constantly reinforcing these messages, unwanted pregnancies and various other issues are reduced. But the cost of this constant reinforcement is that when we do see teenage mothers, even those who deliberately made the choice to have a child, we automatically see them as something dirty, or something to be pitied, which is a tragedy.
Do I think teenage pregnancies are a good idea? In most cases, no. Even if you are financially secure, which is a rare thing for your average teen, a child is a huge commitment, and one that binds you to your partner, so if things don't work out, the child may suffer greatly. And while I believe that a bad mother will always be a bad mother, no matter the age, most people need to experience more of life themselves before try to teach a child about it. Do I think teenage pregnancies, particularly planned ones, are particularly bad? Again, no. As someone who was raised by a teenage mother, and who has a close friend who is one, I can say that teenage mothers are not always bad mothers. Those I have known would lay down their life for their children if necessary, and possess a maturity beyond what you would expect from another their age. That, and the fact that having a mum who would happily play me and my mates at Tekken while I was growing up was, well, pretty damn awesome.
