More specifically, have they been upset because a gift didn't meet their expectation? This question is more for older kids as i never experienced this with my LO until now (4.5 years old).

I was away for a few days and i told DD that i had some surprises for her. For some reason, she had it in her head that i was bringing her princess toys and when she saw the items, she broke down crying and was really upset (e.g., "where are the toys??"). I was really disappointed with her reaction, and it only reinforced my somewhat curmudgeonly views of Christmas and "gift lists" for Santa. Like, if i don't get her all the gifts on her list, what will her reaction be? Catering to her wishes all the time will just make her more spoiled and entitled, won't it?

Has your LO ever reacted this way?
