do your children still believe in santa?

2 of my children still believe in Santa Claus. My oldest son, Joey is 12 and is enjoying keeping the spirit of Christmas alive for his younger brother Justin who's 8 and sister Jenna who's 18 mos. I also am trying to teach the kids about the real spirit of Christmas by helping others in need. My oldest is completely aware of it being giving rather than recieving, as my 2 younger ones get older I'm hoping to instill that into them as well.

My kids are 10 and 12 and I have to say they do still believe. My oldest son at first started saying there isn't a santa so I fixed that. One christmas I had my video camera set up to record the tree and see what my boys did when they got up the next morning. I got to thinking about what daniel said about there not being a santa. So I had my husband dress up and I paused the camera while he got ready when he steped in front of the tree I hit record. When he was done it paused it again and he walked into the bed room. Then I pressed record again when we watched the tape the next morning all you see is the tree then al of a sudden santa appears there placeing gifts under the tree. Well at the end the beard was itching my husbands nose so he started scratching it at the same time I stopped the tape it looks like he just dissapeared. Well now my son believes in santa. because no one can just dissapear.
