Many parents overestimate how much their minor decisions about parenting will affect their children in the long run, leading to unwarranted feelings of guilt. I suggest reading the book "Selfish Reasons to Have More Kids", by Bryan Caplan, discussed at http://giftedissues.davidsongifted.org/BB/ubbthreads.php/topics/98909/1.html .
