It really can be tough. I chose early on no to enforce the belief in Santa and the Tooth fairy. It took on time for my son to question why he wasn't good enough and why Santa didn't bring what he asked for. At the time I was heart broken and didn't know how to explain that Santa is on a tight budget and the Tooth fairy gets paid monthly so she sometimes leaves I.O.Us. It worked out good for our family and both my kids are more understand when it comes to holidays. I make sure they do not ruin it for other kids though. The sad part now is that my daughter is constantly trying to give back her allowance to help with groceries or school clothes. She has a good heart.
