Gabriel, thank you, thank you, thank you, thank you, thank you
for posting this! My wife and I have wanted kids for years (we're still trying to get financially established)... and this video makes us even more eager!... we both specialize in silliness!
When she showed me the video this morning we both laughed for a good solid five minutes, then concluded that it was officially going to be an awesome day!
I don't blame you - it's nice to put at least a little bit of money away as savings "just in case" something comes up and only one of you is working. As the others have said, if you wait until you can "afford" kids, you'll either be waiting until you two are past your child-rearing years, or you won't have any at all. But it is wise to at least make sure you're on somewhat solid ground before taking the plunge.
Just make sure you all are in good health (especially future mommy's teeth!) and have jobs that are solid and you are ahead of the game.
