Dagnabbit. Babies, babies & MORE babies EVERYWHERE!

I'm starting to get a liiiiiittle bit paranoid and out of the loop here. Everywhere I look and everyone around me are sprogging like it's going out of fashion (sprogging = babies for those who were wondering).
Should I? I'm sitting here typing this after spending about 1/2 an hour willing myself to want to have kids. Don't get me wrong. I love children. And, bizarrely, I get along really well with teenagers too - I guess that's from my teaching experience - but I just can't muster up the enthusiasm to foister the progeny of cerebral oddments' and himself, onto the world.
I blame the weather. It's too damn cold in ye olde Englande to have children by my reckoning. And himself doesn't seem to mind terribly either. Maybe my biological clock is broken? Saying that, I got so excited when someone I don't know gave birth! And I do go all gooey and stupid in the presence of babies. And I'm always ready with helpful naming suggestions for boys and girls. "Binky" is my current nom du jour.
Yes, I'm kidding.
But you know what? I'm not going to worry about it. Why? Because I'm only 28 years old for pete's sake. Unless I get run over by a truck, I still have time to have my two kids (there has to be two for symmetry - don't ask..) and at the moment, I really am too busy trying to conquer the world to have time to do the whole nappies and nurturing thing. Because when I'm ready, I'm going to be an old-fashioned mom and I'm going to spend the first 5 years of my kids' lives looking after them and not trying to juggle everything together. Because I don't want to. Which is why I have to conquer the world NOW to give me the time to do what I want to do when I do have kids... or puppies.
