This exact thing happened to me one year. I had finished all my shopping and here is my daughter saying to Santa that the only thing she desperately wanted is the one thing she didnt get. Oh well, we have managed to keep up the Santa story up to now! What I do with my kids is have them make a list of 15-20 items and that way I have plenty of ideas for there grandparents, aunts, uncles, etc..... They usually get everything they want as they arent into extravagent things yet, thank goodnes.
