Holy cow, have you heard about the blogger that said parents of only children are selfish and that only children are obnoxious and have a more selfish nature? I read about it here , and I'm very angry over it! And I don't even have an only child!!
I don't think that people should have more than one child based upon vague assumptions and predictions of behavior. I know plenty of people that weren't only children that are extremely selfish and rude. I think it's on how you are raised and your own genetic makeup, not on how many siblings you have. What do you think about it?
