Congrats! I've got a three year old and she's certainly added a few years to the age of my back, but it's was a happiness engineering optimization that was well worth it =).
Indeed, well there are a few things I should have been told before I became a father -- e.g., how much time I'd spend near the floor of a porta potty with a five year old in a full leg cast -- it is worthwhile and fulfilling. It was not, though, a good way to increase the number of videos I create!
