This is so much like me.  I wasn't planning to but had one anyway.  Funny how that happens sometimes.  The good news is that you love them like nothing else, the bad news is it's just as much of a sacrifice as you feared it would be.  I don't mind though.  I'd do it all over again because the greatest fear in my life now is something happening to him. Strange, isn't it?  It's impossible to fully comprehend this paradox until you've had one. (or it was for me anyway)

I offer no advice to other people about whether or not they should have kids, although I'm always glad to offer advice about how to raise them.  :^)
