I'm in the exact same situation, except we're not at the kid part yet. Apologies to the OP for going off-topic, but I'm glad to hear that we're not the only couple to have waited until their 30s to have kids...in our case we're just not quite settled in our careers yet, but we're getting there. Any problems having kids so late, I mean with regards to the pregnancies?

Okay, now to the original question. That's great that you want to have kids, but wait, man, wait. From a practical standpoint, you want to finish your degree, and having a kid is going to make it tempting to drop out and work full-time in some lousy job to make ends meet. And then you never know what's going to happen post-grad: you might move all over the place before you settle down. That's far from an ideal environment to raise a kid, and you did say that you want to be a responsible father.

Also, you've just started school. You are going to change a lot as a person within the next 4-5 years. You'll see. That doesn't mean that wanting to have kids is a bad thing, but you might find yourself having a different perspective on the issue eventually: maybe you'll decide that you want to travel first, for example.

There's a lot to do in the world and only a limited time to do it before you have to grow up. Don't force things.
