It all depends on your child! LOL! My 8-year old cornered me and asked me point blank 'Is he real or not, I want a real answer'! ROFL!!! Of course, this is the same child that knew characters are people in costume at age 3 and basically he told me he didn't think Santa was real and gave me all the logical reasons - he's always been very analytical, etc...
That being said, he did say it in the car (told him I would tell him later and he wouldn't let it go, kept hounding me around the house after we got home!) and his 10 at the time sister pipped up "I BELIEVE HE IS REAL"

She's also one that doesn't want to grow up and is into the magic of everything (can't wait for the Disney trip to see Pooh bear, etc...). She has known for a long time but she never believed me that it was us.
I have never been one to do Santa up big anyway, he's there and we enjoy the magic of it but I always knew he wasn't real, etc... (Had to ask my mom how I always knew when DD was born because I never had any huge experience with asking my parents or anything, it just always was a given. They just always told us, etc...). That is the same way I have worked it. I know when I told DS - I also told him he couldn't tell any of his friends, they had to ask their own parents.
Although, we have experience "Santa" for real! I also think that is where DD gets it from and she is kind of right. One Christmas we got anonymous gifts donated to us and when DD asked "Who got us these?" - I just told her it was real life Santa's....but it wasn't one person coming down the chimmney - they were left them at the doorstep a few days before.
