Man, and I've got triplets for all intents and purposes....
I seem to recall reading somewhere that the current cost for raising kids through college, not including tuition to that college, will run around $250k per kid.
One of my friends likened raising kids to being pecked to death by a chicken. At times I agree, at others they are my only sanity. At least if I screw them up, they won't realize it until they can pay for their own therapy.
