Well, my first wife had grand-parents that were Jehovah's witnesses (They don't celebrate holidays of any kind) so my daughter never had a real Christmas. Apparently her new fuck-toy and she celebrate Christmas at his parent's house, so they have to tell her about Santa Claus (Don't get me started on my bitter feelings on this). Darth Empyrean and I intend to tell Leia (or Andre if we are having a boy, we have the Ultrasound scheduled for next Monday) all about Santa. We both feel that that is the best thing about being young at Christmas time...
Here's something I take heavily into consideration: One day, my children (whom I have yet to have) will be smart enough to figure out that Santa Claus isn't real. Assuming that I've told them their entire life that he is real, this may be a particularly emotional blow to them. I'm sure they'll get over it eventually, but still, the fact remains that I have lied to my children, again and again even knowing they'd know the truth eventually.
I am a firm believer that the truth takes presidence over emotion at all times. I intend to abstain from any lie that simply makes my kids feel good at the time. This means no Easter-bunny or tooth-fairy. This also means that when good old rover finally dies, I won't tell the kids "oh he is just sleeping." or "He had to go away for a while.". I'll take that opportunity to instill truthful knowledge about the real world (as much of it as I personally understand) into my children rather than delaying the inevitable based on the sensationalism belief that children need to be happy all the time.
