It really isn't if you just treat it as a fun fantasy and don't work too hard to conceal the truth. Kids are happy to believe and have fun with it, and then when they're ready to know the truth, it's fairly obvious. For example, don't try to come up with explanations for inconsistencies or impossibilities, but just ask the kid what they think. Eventually it'll be like, "Well, obviously Santa can't actually come to all the houses, so I think the other Santas help him." "I know you and Mom put our presents under our tree, but I think Santa gives them to you." Etc. They basically explicitly tell you how much Santa they want to believe at any given point. Once they directly ask you if Santa is real, you can ask them if they really want you to answer. (The first time mine quickly said, "No, I know he's real!" and then dropped it for a year. :D ) But if they persist, you can tell them a nice version of the truth, like that the idea of Santa is definitely real, because why else would kids get presents from Santa every year. As they guessed, you help out by actually getting the presents and putting them under the tree, but it's because of this great spirit of giving that so many people feel around Christmas that we have this tradition.
