I may have touched on this in another thread at some point, but a big one for me is parents who go overboard for their kids' birthdays. One of my girl's birthday is the first week of April, just a couple weeks after her cousin's birthday. We have a big family party (four a year, one each season) to celebrate whichever birthdays are closest. I always dread the spring and winter birthdays because of my sister-in-law. She doesn't celebrate her kids' birthdays, or even their birthday weeks (which is bad enough)--she celebrates their birthday months. To be fair, she usually runs out of ideas after a week or so, but she keeps bringing it up and gets annoyed if other people don't get into the spirit. Her kids also can't go to a birthday party without getting a gift of their own. So at this party, not only will her youngest get a present, but her older one will get a present as well. And they have to make a huge deal out of it so that the older one's feelings aren't hurt. We'll go through the same thing again in the winter with the younger one. Also, since their feelings get hurt if anyone else gets anything they don't get (attention, gifts, whatever), they always encourage the other cousins to let their kids help them open their gifts. However, God forbid you even suggest that your kid help open their gifts! We also have to re-light the candles after everyone who is actually celebrating their birthday blows them out (as a group) so that hers can blow them out individually. No matter which one goes first, you can guarantee there's going to be a crying tantrum from the one who goes second. It's lovely. I have to wonder what values this is teaching them.
