holy crap! twins!!!!

My wife and I have been in this fight with nature with the desire to have kids, but dealing with the consquences of thousands of miles on a Mtn. Bike. Naturally in any successful marriage the one at fault is the husband so I'll take the hit on this fault. ANYWAYS. so this 3 year struggle with the emotional battle of we really want 2 kids, but under the circumstances we would be very grateful to have 1. NOW, finally we are looking forward to a family, but It seems we might have our desire for 2, but at the same time. Of coarse we are both excited and very happy, but in between all this joy I think, TWO OF EVERYTHING, TWICE AS MANY AS EVERYTHING, AND NO HAND-ME-DOWNS. If it were to be girls...lotsa lotsa shoes. I'm really concerned about making ends meet. Plus we have a double income now, but would have to go down to a single income We don't have any luxury expenses we can cut out, such as fancy cell phones or a thousand channel cable subscription.
I've been desperatly trying to find something I can suplpiment my icom with on top of my allready 2 jobs. We find out in 12 days how expensive our life is going to become. I think twins would be awsome and make for such a great family, but then I also think from a financial standpoint I hope for 1. I guess thats not our decision to make, but to support.
